MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.

After operation, clean off the blades (both I sides) with a stiff brush. Then wipe the blades with a cloth and coat them with light machine oil.
CAUTION:
Dirt and corrosion cause excessive blade friction and shorten the operating time' per battery charge.
