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 grinder should never be used to set torque. Use a torque wrench to set the torque. Are 
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 drill 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 76.2 mm (3”), 101.6 mm (4”) and 127 mm (5”) grinder, using 9.525 mm 
(3/8”) I.D. fittings with 6.35 mm (I/4") NPT threads are recommended. For 187.8mm (7”) 
grinder, using 12.7 mm (1/2”) I.D. fittings with 9.525 mm (3/8”) 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 15.24 m (50 feet) 
should have a 12.7 mm (I/2") 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 grinder must be lubricated before storing. Following the air motor lubrication Instructions 
with an exception to step 4. Only run the hammer for 2 to 3 seconds instead of 20 to 30 
seconds because more oil needs to remain in the drill when storing.
