INTENDED USE
The impact wrench is designed for the tightening and loosening of threaded fasteners within the range as specified by the manufacturer. It should only
be used in conjunction with suitable impact type 1" (25 mm) or 1 1/2" (38 mm) square female sockets or #5 spline (depending on the model). Only
use sockets which are of the impact type. It is allowed to use suitable extension bars, universal joints and socket adaptors between the square output
drive of the impact wrench and the square female drive of the socket. Do not use the tool for any other purpose than that specified without consulting
the manufacturer or the manufacturer's authorized supplier. To do so may be dangerous. Never use an impact wrench as a hammer to dislodge or
straighten cross threaded fasteners. Never attempt to modify the tool for other uses and never modify the tool for even its recommended use as a
nutrunner.
WORK STATIONS
The tool should only be used as a handheld, hand operated tool. It is always recommended that the tool is used when standing on the solid floor. It can
be used in other positions, but before any such use, the operator must be in a secure position having a firm grip and footing and be aware that when
loosening fasteners the tool can move quickly away from the fastener being undone. An allowance must always be made for this rearward movement
so as to avoid the possibility of hand/arm/body entrapment.
GENERAL OPERATION
The output of the impact wrench in prime working condition is governed by mainly three factors:
a) the input air pressure;
b) the time the impact wrench is operated on the joint. Normal time for joints of average tension requirement 3 to 5 seconds;
c) the setting of the air regulator for a given joint at a given pressure operated for a given time.
The air regulator on throttle handle (25) can be used to regulate the output of the impact wrench if no other means of control is available. It is strongly
recommended that an external pressure regulator, ideally as part of a filter/regulator/lubricator (FRL), is used to control air inlet pressure so that the
pressure can be set to help control the tension required to be applied to the threaded fastener joint. There is no consistent, reliable torque adjustment
on an impact wrench of this type. However, the air regulator can be used to adjust torque to the approximate tightness of a known threaded joint. To set
the tool to the desired torque, select a nut or screw of known tightness of the same size, thread pitch and thread condition as those on the job. Turn air
regulator to low position, apply wrench to nut and gradually increase power (turn regulator to admit more air) until nut moves slightly in the direction it
was originally set. The tool is now set to duplicate that tightness, note regulator setting for future use. When tightening nuts not requiring critical torque
values, run nut up flush and then tighten an additional one-quarter to one-half turn (slight additional turning is necessary if gaskets are being clamped).
For additional power needed on disassembly work, turn regulator to its fully open position. This impact wrench is rated a 1" (25 mm) bolt size. Rating
must be downgraded for spring U bolts, tie bolts, long cap screws, double depth nuts, badly rusted conditions and spring fasteners as they absorb
much of the impact power. When possible, clamp or wedge the bolt to prevent springback. Soak rusted nuts in penetrating oil and break rust seal
before removing with impact wrench. If nut does not start to move in three to five seconds use a larger size impact wrench. Do not use impact wrench
beyond rated capacity as this will drastically reduce tool life.
NOTE: Actual torque on a fastener is directly related to joint hardness, tool speed, condition of socket and the time the tool is allowed to impact. Use
the simplest possible tool-to-socket hook up. Every connection absorbs energy and reduces power.
Forward/reverse operator is controlled by reverse switch (25) located on bottom of throttle housing. Press reverse switch (25). The tool is now
in reverse mode. Press reverse switch the oposite direction and the tool is now in forward mode. Ensure that the reverse switch is in the proper
position before starting tool. The air regulator controls the speed of the tool and is located on the bottom throttle handle (25). For Forward Operation,
it is a 3-position regulator with "3" being the highest setting and "1" the lowest setting. For Reverse Operation, no regulator being applied and fixed to
the highest torque setting.
The tool incorporates an air inlet bushing (51). Check periodically to see if this is becoming blocked as blockage will reduce the speed and power of
the tool. To clean the air inlet bushing it is necessary to remove t he air inlet bushing (51) from throttle handle (24)
For best results:
1) Always use the correct size impact type socket.
2) Use extra deep sockets in place of extension bars where possible.
3) Do not use oversized, worn or cracked sockets.
4) Hold the wrench so the socket fits squarely on the fastener. Hold the wrench firmly, but not too tightly, pressing forward slightly.
AIR SUPPLY
Use a clean lubricated air supply that will give a measured air pressure at the tool of 90 p.s.i./6.2 bar when the tool is running with the trigger fully
depressed and the air regulator in its maximum opening flow position. It is recommended that the tool is connected to the air supply as shown in
figure 1. Do not connect the tool to the air line system without incorporating an easy to reach and operate air shut off valve. The air supply should be
lubricated. It is strongly recommended that an air filter, regulator, lubricator (FRL) is used, as shown in Figure 1, as this will supply clean, lubricated air
at the correct pressure to the tool. Details of such equipment can be obtained from your supplier.
HOSE AND HOSE CONNECTIONS
The air supply hose recommended is 1" (26 mm) I.D. If an extension hose is necessary, use 1+" (26+ mm) ID hose with couplings not less than
1+" (26+ mm) I.D.
