serious injury. The pump, piston components and all electrical parts should be serviced only by authorized repair shop,
dealer or distributor.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.

like. Discoloration, deformation or cracks may result.
