CAUTION:
Always press the shoe firmly against the workpiece
during operation. If the shoe is held away from the
workpiece during operation, strong vibration and/or
twisting will be produced, causing the blade to snap
dangerously.
Always wear gloves to protect your hands from hot flying
chips when cutting metal.
Be sure to always wear suitable eye protection which
conforms with current national standards.
Always use a suitable coolant (cutting oil) when cutting
metal. Failure to do so will cause premature blade wear.
Press the shoe firmly against the workpiece. Do not allow the
002513
tool to bounce. Bring the blade into light contact with the
workpiece. Turn the tool on and wait until the blade attains
full speed. Then apply pressure to cut the workpiece.
NOTE:
If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for 15
minutes before proceeding with a fresh battery.
CAUTION:
Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.
To maintain product SAFETY and RELIABILITY, repairs, any
other maintenance or adjustment should be performed by
Makita Authorized or Factory Service Centers, always using
Makita replacement parts.
