4. OPERATING INSTRUCTIONS
WARNING! Ensure you read, understand and apply safety
p
instructions fore use.
4.1.
Assembly.
4.1.1. Apply appropriate sanding pad to the backing disc. Use only pads with speed
ratings equal to or higher than the speed rating of the sander. DO NOT use cloth
backed sanding pads.
4.1.2. Connect air supply to sander and press the control valve lever and check
that the sander is working correctly.
4.1.3. The air flow may be regulated by turning the control knob on the side of the handle.
4.2.
Operating.
The sander is designed to provide two sanding actions, "rotary" and "random orbit". These actions are controlled
by the spindle lock position (fig 3). For a random orbit, turn the spindle lock so that the flat (A) faces the drive
spindle (B). For rotary action turn the spindle lock so the flat is away from the drive spindle.
Always use grit pad appropriate for the job. Work progressively from coarse grades to finer grades. DO NOT go
from coarse to fine in one step as it may be difficult to remove swirl marks left by the coarser grit.
DO NOT apply excessive pressure, let the sander do the work for you. Start the sander and bring the sanding disc
to the the work surface evenly and slowly. Move the sander back and forth in overlapping areas. Remove the
sanding disc from the work surface before stopping the sander. Regularly check the sanding pad for wear, always
changed a cracked or damaged pad.
DO NOT allow sander to run in "idle rotation" for an extended period of time as this will shorten life of bearings.
5. MAINTENANCE
WARNING! Disconnect sander from air supply before changing accessories, servicing or performing
p
maintenance. Replace or repair damaged parts. Use genuine parts only. Non-authorised parts may be
dangerous and will invalidate the warranty.
5.1.
Lubricate the air sander daily with a few drops of good grade air tool oil such as Sealey ATO/500 or
ATO1000, dripped into the air inlet before use.
5.2.
Clean the sander after use and change pads when required.
5.3.
Loss of power or erratic action may be due to the following:
a) Excessive drain on the air line. Moisture or restriction in the air pipe. Incorrect size or type of hose
connectors. To remedy check the air supply and follow instructions in chapter 3.
b) Grit or gum deposits in the sander may also reduce performance. If your model has an air strainer
(located in the area of the air inlet), remove the strainer and clean it. Flush the sander out with gum
solvent oil or an equal mixture of SAE No 10 oil and kerosene. Allow to dry before use.
If you continue to experience problems, contact your local Sealey service agent.
5.4.
For a full service contact your local Sealey service agent.
5.5.
When not in use, disconnect from air supply, clean sander and store in a safe, dry, childproof location.
