ENGLISH
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 ratchet wrench should never be used to set torque. Use a torque wrench to set the torque
and equip 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 ratchet 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”), 6.35 mm (1/4”) and 9.525 mm(3/8”) ratchet wrench, using 9.525mm
(3/8”) I.D. fittings with 6.35mm(1/4”)NPT threads are recommended. Most compressors are shipped
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 the
other 6.35mm(1/4”) ratchet wrench, using 7.938 mm (5/16”) I.D. fittings with 6.35mm (1/4”) NPT
threads are recommended.
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 ratchet wrench must be lubricated before storing. Follow the air motor lubrication instructions
with an exception to step 4. Let it run only for 2 to 3 seconds instead of 20 to 30 seconds because
more oil needs to remain in the ratchet wrench when storing.
