Release all pressure from the system before attempting to install, service, relocate or per-
forms any maintenance.
16. Keep all nuts, bolts and screws tight and ensure equipment is in safe working condition.
17. Do not put hands near or under moving parts.
18. Speed Adjustment.
The impact wrench should never be used to set torque. Use a torque wrench to set the torque and
equipped with regulators for speed adjustment. To remove nuts, set the regulator to the maximum
setting. To install nuts, set the regulator to the minimum to medium setting. Do not over-tighten the
nuts.
19. Air Hose.
It is not recommended to install a quick coupler between the impact wrench and leader (whip) hose.
Using fittings or air hoses which are too small can create a pressure drop and reduce the power of
the tool. For 12.7 mm(1/2") and 19.05 mm (3/4") impact wrench, using 9.525mm (3/8") I.D. fittings
with 6.35 mm (1/4")NPT threads are recommended. Most compressors areshipped with a short,
6.35 mm (1/4") I.D. hose. For proper performance and more convenience, use a 9.525 mm(3/8")
I.D. hose. Hoses longer than 15.24m (50 feet) should have a 12.7mm(1/2") I.D. For 25.4 mm (1")
Impact wrench, using 12.7mm(1/2") I.D. fittings with 12.7mm(1/2") NPT threads are recommended.
For proper performance and more convenience, use 12.7 mm (1/2") I.D. hose. Hose longer than
15.24m (50 feet) should have a 25.4 mm (1") I.D.
Never carry a tool by the hose or pull the hose to move the tool or a compressor. Keep hoses
away from heat, oil and sharp edges. Replace any hose that is damaged, weak or worn.
20. Storage.
The impact wrench must be lubricated before storing. Follow the air motor lubrication instructions
with an exception to step 4. Only run the impact wrench for 2 to 3 seconds instead of 20 to 30 se-
conds because more oil needs to remain in the impact wrench when storing.
