20. Check damaged parts
Before further use of the tool, a guard or other
part that is damaged should be carefully checked
to determine that it will operate properly and perform its intended function. Check for alignment of
moving parts, binding of moving parts, breakage
of parts, mounting, and any other conditions that
may affect its operation. A guard or other part
that is damaged should be properly repaired or
replaced by an authorized service center unless
otherwise indicated elsewhere in this instruction
manual. Have defective switches replaced by
and authorized service center. Do not use tool if
switch does not turn it on and off.
21. Warning
The use of any other accessory or attachment
other than recommended in this operating
instruction or the catalog may present a risk of
personal injury.
22. Have your tool repaired by an expert
This electric appliance is in accordance with the
relevant safety rules. Repairing of electric appliances may be carried out only by experts otherwise it may cause considerable danger for the
user.
ADDITIONAL SAFETY RULE
1. This is a dry-use tool. Never use water or
coolant. If water or coolant gets into the tool
or offset diamond wheel, damage to the tool
or a dangerous situation may occur.
2. Adequate ventilation of your work area is
very important when using this tool. Use a
dust mask or appropriate respirator.
3. Due to the dusty nature of this tool, be sure
to clean it often to remove dust accumulations. Carefully blow the dust out of the
motor, switch and dust cover areas frequently.
4. Always install the dust cover before operation.
5. Always use Makita offset diamond wheels
only. Never use ordinary diamond wheels
which may be available on the market. Never
use depressed center wheels, cut-off wheels,
or any other type of accessory on this tool.
Failure to do so may result in serious injury
or death to operator or anyone nearby.
6. Check the offset diamond wheel carefully for
cracks or damage before operation. Replace
cracked or damaged wheel immediately.
7. Before using the tool on an actual workpiece,
let it run for a while, keeping it away from
your body. Watch for vibration or wobbling
that could indicate poor installation, a poorly
balanced wheel, or a damaged wheel.
8. Hold the tool firmly with both hands during
operation.
9. Do not leave the tool running unattended.
Operate the tool only when handheld. Do not
fasten or mount the tool to a bench, table or
vise and then introduce workpieces to the
tool.
10. Do not touch the offset diamond wheel immediately after operation; it may be extremely
hot and could burn your skin.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Dust bag installation (Fig.1)
To install dust bag, press bag fitting to inside, open
mouth of bag and slip onto dust port.
Remove dust bag when it begins to touch cutting surface. This is a sign that it is full. Failure to empty bag
will lead to poor suction/pickup.
Replacing diamond wheel (Fig. 2)
Important:
Always be sure that the tool is switched off and
unplugged before replacing the diamond wheel.
To replace a worn diamond wheel with a new one,
press in the shaft lock to hold the shaft steady, then
loosen the lock nut to the left with the lock nut wrench
provided.
NOTE:
The ordinary diamond wheels on the market have no
exhaust holes, so dust evacuation is poor. Also, if the
installing hole is not of the exact diameter, tool vibration occurs and accidents can occur. ALWAYS USE A
MAKITA OFFSET DIAMOND WHEEL.
Switch action (Fig. 3)
CAUTION:
Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
“OFF” position when released.
To start the tool, simply pull the trigger. Release the
trigger to stop. For continuous operation, pull the trigger and then push in the lock button. To stop the tool
from the locked position, pull the trigger fully, then
release it.
Level planing (Fig. 4 &5)
To level a surface, the base of the planer should be
aligned with the diamond wheel. The front roller
should be adjusted (use hex wrench) upward to the
level required for the desired stock removal amount.
6
To change the amount of stock (concrete) removed,
loosen the hex socket head bolts on the grip holder
with the hex wrench. Raise or lower the front roller to
adjust the gap between it and the diamond wheel.
The difference is the stock removal amount. Then
secure the hex socket head bolts very carefully.
NOTE:
Maximum stock removal should be less than 2.5 mm.
Tilting base for smoother planing
For smooth removal of a given surface roughness or
texture, tilting the base is helpful. Use the hex wrench
to loosen the two hex socket head bolts securing the
base on either side. (Fig. 6)
Use a screwdriver to lower the three screws on the
base by turning rightward. (Fig. 7)
Use a square or ruler to obtain the desired base
angle in relation to the diamond wheel. Then secure
carefully the hex socket head bolts on either side of
the base. Adjust center of base near wheel so that it
is on the same level as the wheel. (Fig. 8)
NOTE:
After base adjustment, turn the three screws leftward
on base until the hands are flush with the back side
of the base. Turn gently or base adjustment will be
thrown off. (Fig. 7)
Base adjustment to compensate for wheel
wear (Fig. 6& 7)
With long use, the diamond wheel will wear and thus
create a gap with the planing surface so that performance becomes poor. Check the tool after every 4 or
5 hours of use. If the wheel and base surfaces are
not aligned, loosen the hex socket head bolts securing the base. Turn the screws on the base to the right
and adjust the base so as to be level with the wheel
surface. Retighten the bolts and then gently turn the
screws to the left until flush with the back side of the
base. The screws should not come loose during
operation.
Planing in corners (Fig. 9 & 10)
Flush planing of corners is possible after first removing the dust cover.
Turn dust cover rightward until it stops, light toward
you to remove.
Dust cover adjustment (Fig. 11)
The dust cover should be either flush with the diamond wheel surface or very slightly above (when tool
is inverted) 0.5mm. Suction/pickup will be poor if they
are not approximately on the same level.
To adjust the dust cover, grip it on the outside; turn
right to raise, left to lower.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Replacement of carbon brushes (Fig. 12 &13)
Replace carbon brushes when they are worn down to
the limit mark. Both identical carbon brushes should
be replaced at the same time.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by
a Makita Authorized Service Center.
