Maintenance - Makita BBC300LRDE Instruction Manual

MAINTENANCE

CAUTION:
• Always be sure that the equipment is switched off and
the battery cartridge is removed before attempting to
perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Supply of grease to gear case (Fig. 31)
Supply grease (Shell Alvania 2 or equivalent) to the gear
case through the grease hole every 30 hours. (Genuine
Makita grease may be purchased from your Makita
dealer.)
Replacing the nylon cord
WARNING:
• Release the switch trigger and remove the battery pack
before replacing nylon cord.
• Make sure that the cover of the nylon cutting head is
secured to the housing properly as described below.
Failure to do so may make it fly apart and cause
serious injury. (Fig. 32)
Press on the housing latches inward to lift off the cover,
then take the spool out and remove the remaining nylon
cord on it. (Fig. 33)
Hook the center of new nylon cord into the notch in the
center of the spool, with one end of the cord extending
about 80 mm more than the other.
Then wind both ends firmly around the spool in the
direction of the head rotation (left-hand direction indicated
by LH and right-hand direction by RH on the side of the
spool). (Fig. 34)
Wind all but about 100 mm (3-15/16") of the cords, leaving
the ends temporarily hooked through a notch on the side
of the spool. (Fig. 35)
Mount the spool in the housing so that the grooves and
protrusions on the spool match up with those in the
housing. Keep the side with letters on the spool visible on
the top. Now, unhook the ends of the cord from their
temporary position and feed the cords through the eyelets
to come out of the housing. (Fig. 36)
Align the protrusion on the underside of the cover with the
slots of the eyelets. Then push cover firmly onto the
housing to secure it. Make sure the latches fully spread in
the cover.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
