MAINTENANCE
IMPROPERLY MAINTAINED TOOLS CAN CAUSE SERIOUS INJURIES
TO TOOL OPERATOR AND BYSTANDERS –
CLEAN TOOL DAILY
Always make sure the tool is not loaded before performing any service or repair and
always wear approved eye protection when cleaning or servicing the tool.
DAILY CLEANING
All front end parts shown in the disassembly section are to be cleaned daily with a good
detergent oil and wire brush. Remove all dirt and carbon buildup and wipe parts dry with a
clean rag. Check all parts for wear or damage before reassembly and replace or repair any
worn or damaged parts.
PERIODIC COMPLETE CLEANING / GENERAL MAINTENANCE
Heavy or constant exposure to dirt and debris may require that the tool be cleaned
more extensively. Complete disassembly and cleaning of all parts may be necessary to
restore the tool to normal operation. General maintenance should be performed every six
months or more often if the tool is subjected to heavy use. General maintenance/complete
cleaning should be done by a qualified repair person.
ALWAYS FUNCTION TEST THE TOOL AFTER PERFORMING ANY
SERVICE. SEE PAGE 9 FOR DETAILS ON THE FUNCTION TEST.
