Electronic function
The tools equipped with electronic function are easy to
operate because of the following features.
Constant speed control
Possible to get fine finish, because the rotating speed is
kept constant even under the loaded condition.
Soft start feature
Soft start because of suppressed starting shock.
ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
Installing the backing pad
► Fig.10: 1. Hex wrench 2. Bolt 3. Backing pad
Put the backing pad on the shaft then turn the bolt
clockwise with a hex wrench.
CAUTION:
Make sure that the backing pad is
secured properly. Loose attachment will run out of
balance and cause an excessive vibration which may
cause loss of control.
Installing side grip
Optional accessory
CAUTION:
Tighten the caps or side grip
firmly. Otherwise, the front cover may fall and cause
an injury.
► Fig.11: 1. Cap 2. Side grip
Remove the cap and screw the side grip on the tool
securely.
The side grip can be installed on either side of the tool.
Installing or removing pad
Optional accessory
CAUTION:
Only use hook-and-loop system
pads for polishing.
► Fig.12: 1. Pad
To install the pad, first remove all dirt and foreign mat-
ter from the hook-and-loop system of the pad and the
backing pad. Attach the pad to the backing pad so that
their edges are aligned.
To remove the pad from the backing pad, just pull up
from its edge.
CAUTION:
Make sure that the pad and
backing pad are aligned and securely attached.
Otherwise the pad will cause an excessive vibration
which may cause loss of control or the pad may be
thrown out from the tool.
OPERATION
CAUTION:
Only use Makita genuine pads for
polishing (optional accessories).
CAUTION:
Make sure the work material is
secured and stable. Falling object may cause
personal injury.
CAUTION:
Hold the tool firmly with one hand
on the switch handle and the other hand on the
front grip (or side handle) when performing the
tool.
CAUTION:
Do not run the tool at high load
over an extended time period. It may result in tool
malfunction which causes electric shock, fire and/or
serious injury.
CAUTION:
Be careful not to touch the rotating
part.
CAUTION:
Before operating the tool, make
sure that the side grip or caps are not loose. If the
side grip or caps are loose, the front cover may fall
and cause an injury.
NOTICE:
Never force the tool. Excessive pressure
may lead to decreased polishing efficiency, damaged
pad, or shorten tool life.
NOTICE:
Continuous operation at high speed
may damage work surface.
Polishing operation
► Fig.13
1. Surface treatment (Random orbit with forced
rotation mode)
Use a wool pad for rough finishing then use a sponge
pad for fine finishing.
2. Applying wax (Random orbit mode)
Use a sponge pad. Apply wax to the sponge pad or
work surface. Run the tool at low speed to smooth out
wax.
CAUTION:
Do not apply excessive wax or
polishing agent. It will generate more dust and may
cause eye or respiratory diseases.
NOTE: First, perform a test waxing on an inconspic-
uous portion of the work surface. Make sure that the
tool will not scratch the surface or result in uneven
waxing before.
3. Removing wax (Random orbit mode)
Use another sponge pad. Run the tool to remove wax.
4.
Polishing (Random orbit mode)
Apply a felt pad gently to the work surface.
