MAINTENANCE WORK AND REPLACEMENT OF WEARING PARTS

It takes only a minimal amount of time to inspect the machine,

but this precautionary measure can save subsequent complaints

brought about by minor damage to the machine. Performing regular

maintenance work will help to retain the value of the machine and

is also in the interests of your own safety.

7.1 CLEANING AND CARE INSTRUCTIONS

WARNING!

RISK OF FIRE from spontaneous combustion and the formation

of sparks while sanding:

• There is a high risk of fire when sanding woods with a

large amount of resin, oiled or waxed floors or metal!

Therefore, the machine must always be cleaned carefully
directly after sanding!

• Be certain to note the warning notices of the manufacturers

of the paint, oil and wax!

RISK OF PROPERTY DAMAGE:

• Never use any cleaning products which contain solvents!

7.1.1 GENERAL

Before starting work, you should perform the following care

procedure in order to ensure that the machine is in full working

order and produces the customary high-quality sanding finish:

•

Check the tensioning roller and the sanding drum for damage.

Clean the parts carefully and ensure that the rubber coating

on the rollers is not damaged!

•

Check the sanding belt tracking and adjust it if necessary

using a grit grade 120 sanding belt (

Section 7.3, Checking

and setting the sanding belt tracking

•

Check if the guide rollers at the drive unit and inside the

machine housing are rotatable easily!

Guide rollers which are not rotatable easily provoke
sparking during sanding and must be replaced without fail
