SECTION 6: MAINTENANCE
General
The Flap/Drum Sander is ruggedly constructed to provide years of dependable service. To ensure that you enjoy maximum performance and longevity, we suggest the following routine main- tenance:
1.Check all fasteners for tightness before each use. Tighten when necessary.
2.Keep the Sander clean for maximum effi- ciency and heat dissipation. Wipe away accumulated sanding dust and grime after each use.
3.Inspect sanding sleeves for excessive wear and damage. Replace if necessary.
4.Inspect the switch and cord periodically for wear or damage. Replace if necessary.
5.Bearings are sealed and permanently lubri- cated, so no further lubrication is needed. Check for wear periodically and replace when worn. Increased motor noise and vibration are both indicators of bearing wear.
DO NOT make adjustments or attempt any maintenance procedures while this machine is running. Ensure that the switch is off, power is disconnected and all mov- ing parts have stopped before making adjustments. Failure to do so could result in serious operator injury.
Mounting Sleeves
on Drums
The Sander is supplied with two different sizes of inflatable drums, one 43Ú4" in diameter, the other 31Ú2" in diameter. To remove the sleeve, first de- inflate the rubber drum by pressing on the plunger in the center of the air valve with a nail or paper clip. With a bit of coaxing the abrasive sleeve should come loose. See Figure 10.
After selecting the desired grit and backing type (hard or soft), check the inside diameter of the sleeve for the direction arrows. Determine which spindle, left or right, you intend to install the drum assembly onto. Make certain the rotation of the abrasive sleeve agrees with the direction of rota- tion of the spindle. Remember the air valve will always be facing away from the machine when the drum is installed.
Now inflate the drum by attaching a hand pump (e.g. as bicycle tire pump) to the valve and inflat- ing to a maximum of 10 PSI. Pressure any higher can result in damage to the drumÕs seals. Install the drum onto the motor spindle.
