If your Air Tool is not working like it used to, there are a few things you may check before you throw it in the dumpster. If you are experiencing low power on your air impact wrench, here are three easy steps:

* The first problem could be a dirty inlet bushing or air strainer screen. Just simply clean both of these with a suitable cleaning solution.

* Next, examine the cylinder. Replace it if it is worn or broken or if the bore is scored or wavy.

* Finally, disassemble the tool and clean all parts with a suitable cleaning solution in a well ventilated area. Reassemble the tool according to manual.

These three easy steps can solve low power problems most of the time. If your impact wrench is not impacting properly, try this. Check and make sure the air tool has been properly lubricated. Lubrication is absolutely critical to maintaining your air tools at peak performance. To resolve lack of lubrication, remove the hammer case and lubricate the mechanism. Once the hammer case has been removed inspect the impact wrench mechanism parts. Replace any broken or worn parts. Most manufacturers include detailed instructions on how to do this procedure in the manual. These are a few easy procedures that can extend the life of your Air Tool and restore it to its original working condition.

Pneutrend Air tools are robust and of long durability, having been developed and built for continuous usage under most extreme conditions. Though even the best tool can not survive continuous neglect and wrong usage. To maintain the function and the performance of your air tool the following points have to be taken note of:

1) Air tools have to be kept clean and sufficiently oiled. At the end of each working day the tool has to be oiled through the air inlet with a few drops of hydraulic oil, running the tool at free speed a few times, to distribute the oil evenly in the rotor. This procedure prevents the tool from rusting inside before next use.

2) For an unproblematic usage of air tools clean air is being needed. Remains of corrosion, dust and dirt off the air supply line affect the power and cause technical problems. A service unit consisting of a filter, a reducing valve and an oiler extract the dampness and the dirt out of the air, regulating the working pressure and supplying the tool with the maintenance oil.

3) Low operating pressure reduces the power and the free speed of your tool. Always provide for the correct operating pressure of a minimum of 6 bars and a sufficient compressor with corresponding air container.

The following formula will help you in determining the air consumption of your tool, respectively the size for your needed compressor:

Working time =

Container volume x (turn off pressure - working pressure of tool)

Air usage – Supply quantity

Examples:

a) Air usage of tool = 350 l/min at 6 bar

Supply quantity of compressor = 350 l/min

Turn off pressure = 10 bar

Container = 500 l

Working time =

500 x (10 – 6) = infinite

350 – 350

Meaning infinite usage as no air is being used out of the container.

b) Same as above but with compressor 250 l/min

Working time =

500 x (10 – 6) = 20 min

350 – 250

Meaning that the tool can be used continuously for 20 minutes.

c) Observe the decrease (loss) of pressure in the supply line. A hose, for example, of 10 m length and 10 mm inner diameter with an air quantity of 1,0 m3 looses 1,4 bar. To be able to operate the tool with 6 bar, it would be necessary to adjust the pressure to 7,4 bar to compensate the loss in the following 10 m hose.

4) Service your air tool regularly. As with your car, your tool requires service in regular intervals. Our contract workshop guarantees quick and reliable service so that your tool can bring the full power.

5) Supply lines, connections and couplings have to be sufficiently dimensioned as they are crucial for the free speed per minute and the power.

6) Impact sockets are indispensable for the usage of Impact Wrenches of any size. In no case use impact sockets for hand tools: these are “glass hard” and could break during first usage, possible causing serious injuries.

7) The free speed per minute information of the PNEUTREND air tools have been measured under an operating pressure of 6,3 bar. Each increase of the operating pressure increases at the same time the free speed per minute and the power. Apart from the overwork of the tool and the shortening of its service life, the accessories such as the sanding paper, the Roloc Bristle Discs, the cutter, the saw blades or similar parts are being over-stressed. If the stated highest free speed per minute (load limit) is being passed, then the user is in acute danger.

8) Always wear protection glasses when using handheld tools.

Impact Wrenches

PNEUTREND offers a large variety of Impact Wrenches for various operating areas. From the smallest 3/8” Impact Wrench for usage in car body repair stations up to the large 1½” Impact Wrench for repairs of trucks and construction machines PNEUTREND offers a maximum of handiness, robustness and power. Considering the newest technical designs and usages of a modern PNEUTREND pin clutch mechanism system we are able to cover all requirements in the ½”, ¾” and 1” square drive range for fast torque build up (less tiring handling and almost vibration free working due to the specifically constructed and vibration damped clutch system).

The following points have to be considered, to obtain the best possible application results:

With the Impact Wrenches which are normally being used in the repair area it is not possible to adjust a specific torque exactly. They are only adjustable to a certain degree by the air regulator or the throttle valve.

For the purposes of an equivalent measurement basis all torque data for the PNEUTREND Impact Wrenches is based on so-called “hard screw-cases” and high-rigidity screws.

All quoted values are often not achieved in practice because the following factors cause a considerate loss of torque:

So-called “soft screw cases”, means when gaskets or other materials which are elastic or can be deformed permanently (such as spring washer or waved washer), are being used for the clamping. It is impossible to build up the required pre-tension.

A higher friction will be reached by using screws and materials of different hardness, which create a higher torque, even without the screw being tightened any more.

The working pressure being too low, respectively insufficient air quantity directly at the tool:

The air hose diameter is too small.

If no service unit is attached, water and dirt can enter without any problem, causing fast wear

off and rust. Lack of oil can cause tool break down too early.

The usage of old impact sockets worn out at the female hexagon and square drive, make on one hand a slippage between the screw and the nut possible as well as on the square drive. Loss of power, torque dispersion and above-average wear off at the tools clutch system are the consequence.

Extensions and joints alter the torque values of an Impact Wrench by up to 50% depending on the length and condition. Due to the usage of high performance clutch system the power of most quality impact wrenches increases in proportion to the time of action, whereby the time factor is of important significance when determining the torque which can hardly be taken into consideration in the repair shop practice.

The advantage of the PNEUTREND Impact Wrench in comparison to conventional working methods is clearly the ideal relation between weight and power performance. The high torque required for tightening and loosening of large screw connections are being created by the PNEUTREND Impact Wrenches almost without any back kick. Therefore there are no restrictions in regards to torque limitation and applications.

Ratchet Wrenches

PNEUTREND Ratchet Wrenches are available with ¼”, 3/8” and ½” square drive. All Ratchet Wrenches can be operated with hand sockets as these are slow turning screw drivers and not Impact Wrenches. The stated power causes a back kick, as it does occur with all powered screw drivers, which has to be absorbed by the user. The power therefore is only a fraction of power of a similar impact wrench.

The application area for Ratchet Wrenches is therefore completely different. Their advantage lies in their enormous handiness in tight and small working areas as well as in their controllable starting torque, comparable to the usage of manual ratchets whereby the time saving totals to 90% in some cases.

Only the Ratchet Impact Wrench with impact clutch in front of the rotor has an exceptional position. Because of this there is no back kick and the power is considerably higher than with a normal Ratchet Wrench.

Sanders and Polishers

The PNEUTREND program features more than 30 Sanders. This large selection offers a wide field of solutions for almost any application work in the area of sanding and polishing.

Due to the ability to adjust the correct free speed through the sensitive speed regulator or the valve, smaller air consumption, noise level and a reduced wear off are guaranteed.

The free speed of all sanders has been measured under a working pressure of 6,3 bar. It has to be avoided to exceed this working pressure, as the free speed would automatically be increased as well. The maximal permitted highest free speed for sanding papers and other accessories could be exceeded which in return could create danger for the user.

A rule of thumb is: The highest permitted free speed for sander accessories should be considerably above the highest free speed of the sander.

Eye protection glasses have to be worn at all times when using Sanders.

Drills

All PNEUTREND Drills are furnished with a planet gear. The planet gear distributes the load evenly onto the bearing and guarantees long durability and low repair costs. Planet gears are a quality mark for good drills.

Drills

Most PNEUTREND Drills can be regulated continuously via the trigger. This means practice met applications in daily usage. PNEUTREND Drills are lighter than comparable electrical drills and guarantee safety against accidents through electric power.

The specific attributes of the power medium compressed air offer a considerate advantage over conventional electric energy.

If the Drill gets stuck the reaction moment of Drill only affects the handle by 1/6th whereby a drill which is being operated electrically, the reaction moment increases several times.

An overload of the air motor to complete standstill is possible without damage to the drill.

Air Drills are safe when used correctly.

Speed regulation is continuously possible without costly gear. This makes a more compact construction possible and the drill is less susceptible.

All PNEUTREND Drills are generally equipped with a quality key chuck or with a keyless drill chuck at extra cost.

Air Hammers

PNEUTREND Air Hammers are available in various power sizes with round or hexagon shank. From the medium size hammer for car body work and 3.300 blows min-1 up to the heavy duty air hammer of 5,8 kg weight and of 2.500 blows min-1. The PNEUTREND program offers a wide variety of the most important air hammers for difficult chisel works. A large assortment of chisels, riveters, retainer springs, quick change chucks and other accessories make the usage of our Air Hammers for almost any application possible.

To guarantee an unproblematic usage of the Air Hammers, the following points should be considered by all means:

Check the tool shank for possible damages before each use.

On a daily basis check the spring retainers, chisel and other accessories for cracks, excessive wear or other physical damage before use. Accessories that show signs of damage should be replaced immediately.

Never use the Air Hammer without retainer spring.

Start the working process slowly thereafter continues to work with increasing speed.

Air Hammers should never be used at free speed.

Always keep the chisels in good condition. Edgeless and worn chisels increase the working process.

Always wear eye protection when working with the Air Hammer.

Furthermore the PNEUTREND program consists of: Belt Sanders, Die Grinders, Tire Buffers, Screw Drivers, Reciprocating Saws, Shears, Nibblers, Air Riveter as well as a large selection of useful accessories.
