MAINTENANCE

• Keep the vents of the sander clean at all times. If possible, prevent foreign
matter from entering the vents.
• After each use, blow air through the sander housing to ensure it is free from
all dust particles which may build up. Build up of dust particles may cause the
sander to overheat and fail.
• If the enclosure of the sander requires cleaning, do not use solvents but a
moist soft cloth only. Never let any liquid get inside the sander; never immerse
any part of the sander into a liquid.
Replacing the Hook & Loop Backing Pad
After considerable use, the hook and loop backing pad (2) surface will
become worn, and must be replaced when it no longer offers a firm grip. The
replacement backing pad can be ordered through the Special Orders Desk at
any Bunnings store.
1. To replace, remove the four philips head screws by rotating anti-clockwise.
2. Place new backing pad on the tool and retighten the four philips head
screws by rotating clockwise.
Carbon Brushes
When the carbon brushes wear out, the sander
will spark and/or stop. Discontinue use as soon
as this happens. They should be replaced prior to
recommencing use of the sander. Carbon brushes
are a wearing component of the sander and are
therefore not covered under warranty. Continuing
to use the sander when carbon brushes need to
be replaced may cause permanent damage to the
sander. Carbon brushes will wear out after many uses. When the carbon
brushes need to be replaced, take the sander to an electrician or a power tool
repairer for a quick and low cost replacement. Always replace both carbon
brushes at the same time.
Note: Ozito Industries will not be responsible for any damage or injuries
caused by the repair of the sander by an unauthorised person or by
mishandling of the sander.

TROUBLE SHOOTING
Sparking visible through the housing air vents
A small amount of sparking may be visible through the housing vents.
This is normal and does not indicate a problem.
Excessive sparking visible through the housing air vents
and/or the sander failing to operate
May indicate the carbon brushes have worn out and need to be replaced. Carbon
brushes should only be replaced by a qualified electrician or power tool repairer.

Sandpaper Selection

Selecting the correct grit of sandpaper is an important step in achieving
optimum results. Coarse grit will remove the most material. Finer grit will
produce a smoother finish. The condition of the workpiece will determine the
grit of the sandpaper to be used. The higher the grit number, the finer the
grade of sandpaper.
If the surface is rough, start with a coarse grit and sand until the surface is
uniform. Medium grit may then be used to remove scratches left by the coarser
grit. Finer grit is then used to finish the surface. Always continue sanding with
each grade of sandpaper until the surface is uniform.

Note: If intermediate sanding is required, choose a grit rating between coarse and
fine. The above table is intended as a guide only. To ensure a satisfactory result,
a small, inconspicuous area should first be tested to ensure the grit of sandpaper
chosen is suitable for the desired finish.

Sanding Tips

Never force the sander. The weight of the sander supplies adequate pressure,
allowing the sandpaper to do the work. Applying additional pressure will slow the
motor, rapidly wear the sandpaper, and greatly reduce the sander speed. This will
slow the removal rate and produce an inferior quality surface.
CAUTION: Excessive pressure will overload the motor, causing possible damage
to the sander by overheating the motor; or damage to the workpiece.
Be sure to check your workpiece often. The sander is capable of removing
material rapidly, especially with coarse paper.
The orbital action of your sander allows you to sand with the grain, or at any angle
across it for most sanding jobs. In the final stages a better finish will be achieved
by sanding with the grain.
Do not sand on one spot for too long. The sander's rapid action may remove too
much material, creating an uneven surface.
