Work Stations

The tool should only be used as a hand 

held hand operated tool. It is always rec-

ommended that the tool is used when 

standing on a solid floor. It can be used 

in other positions but before any such 

use the operator must be in a secure 

position having a firm grip and footing 

and be aware of the safety rules to be 

obeyed when using the sander.

Foreseen Use of the Tool

This angle sander is designed for use with 5" diameter coated 

abrasive discs of various grades of grit which are designed to be 

used at the same or higher speed of this tool. The spindle thread 

is 5/8 - 11 UNC-2A and the tool can be used with other 

abrasive devices that have the same female thread size and are 

designed to run without a guard and have a rated speed equal 

to or higher than the speed of the tool. Do not attempt to use 

any bonded abrasive devices, i.e. grinding wheels, as those 

which could be fitted because of their size, cannot be used 

without a suitable guard. A guard is not available for this tool.

Do not fit any form of saw blade.

Do not fit any other abrasive or cutting device before checking 

the suitability for use with this tool with the manufacturer or the 

manufacturer's authorised distributor.

Do not modify this tool for other use, or for its use as a sander 

before checking the intended alternative use with the 

manufacturer or his authorised distributor.

Putting Into Service

Air Supply

Use a clean lubricated air supply that will give a measured air 

pressure at the tool of 90lb p.s.i./6.3 bar when the tool is 

running with the trigger/lever fully depressed. Use 

recommended hose size and length. It is recommended that the 

tool is connected to the air supply as shown in figure 1. Do not 

connect the tool to the air line system without incorporating an 

easy to reach and operate air shut off valve. The air supply 

should be lubricated. It is strongly recommended that an air 

filter, regulator, lubricator (FRL) is used as shown in Figure 1 as 

this will supply clean, lubricated air at the correct pressure to the 

tool. Details of such equipment can be obtained from your 

supplier. If such equipment is not used then the tool should be 

lubricated by shutting off the air supply to the tool, 

depressurising the line by pressing the trigger on the tool. 

Disconnect the air line and pour into the intake bushing a 

teaspoonful (5ml) of a suitable pneumatic motor lubricating oil
