Makita JR140D MAINTENANCE

Press the shoe firmly against the workpiece. Do not allow the

tool to bounce. Bring the blade into light contact with the

workpiece. First, make a pilot groove using a slower speed.

Then use a faster speed to continue cutting.

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.

MAINTENANCE CAUTION:

•Always be sure that the tool is switched off and the

battery cartridge is removed before attempting to

perform inspection or maintenance.

Remove and check the carbon brushes regularly. Replace

when they wear down to the limit mark. Keep the carbon

brushes clean and free to slip in the holders. Both carbon

brushes should be replaced at the same time. Use only iden-

tical carbon brushes.

Use a screwdriver to remove the brush holder caps. Take out

the worn carbon brushes, insert the new ones and secure

the brush holder caps.

After replacing brushes, insert the battery cartridge into the

tool and break in brushes by running tool with no load for

about 1 minute. Then check the tool while running and elec-

tric brake operation when releasing the switch trigger. If elec-

tric brake is not working well, ask your local Makita service

center for repair.

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.
