Operation; Maintenance; Optional Accessories - Makita HM0810T Betriebsanleitung

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing side grip (auxiliary handle) (Fig. 2)
The side grip swings around to either side, allowing easy
handling of the tool in any position. Loosen the side grip
by turning it counterclockwise, swing it to the desired
position and then tighten it by turning clockwise.
Bit grease (optional accessory)
Coat the bit shank head beforehand with a small amount
of bit grease (about 0.5 – 1 g; 0.02 – 0.04 oz.). This
chuck lubrication assures smooth action and longer serv-
ice life.
Installing or removing bit (Fig. 3 & 4)
Pull the change ring down all the way and insert the bit
into the tool holder as far as it will go. Release the
change ring and it will return automatically to its original
position to secure the bit. After installing, always make
sure that the bit is securely held in place by trying to pull
it out.
To remove the bit, pull the change ring down all the way
and pull the bit out.

OPERATION

Chipping / Scaling / Demolition
Hold the tool firmly with both hands. Turn the tool on and
apply slight pressure on the tool so that the tool will not
bounce around, uncontrolled. Pressing very hard on the
tool will not increase the efficiency.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing carbon brushes (Fig. 5, 6 & 7)
When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically
shut off the motor. When this occurs, both carbon
brushes should be replaced. Keep the carbon brushes
clean and free to slip in the holders. Both carbon brushes
should be replaced at the same time. Use only identical
carbon brushes.
Use a hex wrench to remove the rear cover.
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.
Lubrication (Fig. 8 & 9)
This tool requires no hourly or daily lubrication because it
has a grease-packed lubrication system. It should be
relubricated after every 6 months of operation. Send the
complete tool to Makita Authorized or Factory Service
Center for this lubrication service. However, if circum-
stances require that you should lubricate it by yourself,
proceed as follows.
Run the tool for several minutes to warm it up. Switch off
and unplug the tool.
Remove the crank cap using a Makita lock nut wrench 35
(optional accessory). Rest the tool on the table with the
bit end pointing upwards. This will allow the old grease to
collect inside the crank housing.
Wipe out the old grease inside and replace with a fresh
grease (30 g; 1 oz). Use only Makita genuine hammer
grease (optional accessory). Filling with more than the
specified amount of grease (approx. 30 g; 1 oz) can
cause faulty hammering action or tool failure. Fill only
with the specified amount of grease.
Reinstall the crank cap and tighten with the lock nut
wrench.
CAUTION:
• Do not tighten the crank cap excessively. It is made of
resin and is subject to breakage.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
