performs any maintenance.

17. Do not put hands near or under moving parts.

18. Air Hose
It is not recommended to install a quick coupler between the hammer 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 most of the hammers, using 9.525 mm (3/8") I.D. fittings with 6.35 mm
(I/4") NPT threads are recommended. For the others hammer, using 12.7 mm( 1/2") I.D. 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.

19. Storage
The scaling hammer must be lubricated before storing. Follow the air cylinder lubrication
instructions with an exception to step 4. Only run the scaling hammer for 2 to 3 seconds
instead of 20 to 30 seconds because more oil needs to remain in the scaling hammer when
storing.
