SAFETY INSTRUCTIONS FOR SANDERS

WARNING: 

Do not operate this tool until it is 

completely assembled and installed accord-

ing to the instructions.

1.  Hold your power tool by the insulated gripping 

surfaces, especially when performing an opera-

tion where the sanding accessory could contact 

hidden wiring.

2.  Protect your lungs. Wear a face or dust mask 

during operation. Following this rule will reduce 

the risk of serious respiratory injury.

3.  Protect your hearing. Wear hearing protection 

during extended periods of operation. Following 

this rule will reduce the risk of serious personal 

injury.

4.  Inspect power cords periodically and repair them 

as needed at your nearest authorized service 

center. Constantly stay aware of cord location. 

Following this rule will reduce the risk of electric 

shock or fire.

5.  Check damaged parts. Before further use of 

the tool, determine that it will operate proper-

ly and perform its intended function. Check for 

alignment, binding or breakage of moving parts 

or  any  other  conditions  that  may  affect  its  op

-

eration. A guard or other part that is damaged 

should be properly repaired or replaced by an 

authorized service center. Following this rule will 

reduce the risk of shock, fire, or serious injury.

6.  Remove all nails from lumber before using this 

tool.

7.  Do not use the sander to remove lead-based paints.

WARNING: 

This product and the dust creat-

ed by power sanding, sawing, grinding, drill-

ing, and other construction activities may 

contain chemicals, including lead, can cause 

cancer, birth defects, or other reproductive harm. 

Wash hands after handling.

f

Some examples of these chemicals are:

ƒ

lead from lead-based paints

ƒ

crystalline silica from bricks and cement and oth-

er masonry products

ƒ

arsenic and chromium from chemically treated 

lumber.

f

Use the machine only for dry sanding. Penetration 

of water into the machine increases the risk of an 

electric shock.

CAUTION,  FIRE  HAZARD!

 Avoid overheating the 

object  being  sanded  as  well  as  the  sander. 

Always empty the dust collector before tak-

ing breaks. In unfavourable conditions, e. g., 

when sparks emit from sanding metals, 

sanding debris in the dust bag, micro filter or paper 

sack  (or  in  the  filter  sack  or  filter  of  the  vacuum 

cleaner) can self-ignite. Particularly when mixed 

with remainders of varnish, polyurethane or other 

chemical materials and when the sanding debris is 

hot after long periods of working.

f

Secure the workpiece. A workpiece clamped with 

clamping devices or in a vice is held more secure 

than by hand.

VIBRATION SAFETY 

This tool vibrates during use. Repeated or long-term 

exposure to vibration may cause temporary or per-

manent  physical  injury,  particularly  to  the  hands, 

arms and shoulders.

TO REDUCE THE RISK OF ANY VIBRATION-RE-

LATED INJURY:

ƒ

First be examined by a doctor and then have regu-

lar medical check-ups to ensure medical problems 

are not being caused or worsened from use. Preg-

nant women or people who have impaired blood 

circulation to the hand, past hand injuries, nervous 

system disorders, diabetes, or Raynaud's Disease 

should not use this tool. If you feel any symptoms 

related to vibration (such as tingling, numbness, 

and white or blue fingers), seek medical advice as 

soon as possible.

ƒ

Use tools with the lowest vibration when there is 

a choice.

ƒ

Take vibration-free breaks during each day of work.

ƒ

Grip tool as lightly as possible (while still keeping 

safe control of it). Let the tool do the work.

CONNECTION TO THE POWER SUPPLY

Make sure the power supply information on the ma-

chine's rating plate are compatible with the power 

supply you intend to connect it to. 

This appliance is Class II* and is designed for connec-

tion to a power supply matching that detailed on the 

rating label and compatible with the plug fitted. If 

an extension lead is required, use an approved and 

compatible lead rated for this appliance. Follow all 

the instruction supplied with the extension lead.

*Double insulated   : This product requires no 

earth connection as supplementary insulation is 

applied to the basic insulation to protect against 

electric shock in the event of failure of the basic 

insulation.

GUIDELINES FOR USING EXTENSION CORDS

f

Make sure your extension cord is in good condition. 

When using an extension cord, be sure to use one 

heavy enough to carry the current your product 

will draw. An undersized cord will cause a drop in 

line voltage resulting in loss of power and over-

heating. 

f

Always replace a damaged extension cord or have 

it repaired by a qualified person before using it.

f

Protect  your  extension  cords  from  sharp  objects, 

excessive heat and damp/wet areas.

f

Use a separate electrical circuit for your tools. This 

circuit should be protected with the appropriate 

time-delayed fuse. Before connecting the motor 

to the power line, make sure the switch is in the 

OFF position and the electric voltage is rated the 

same as the voltage stamped on the motor name-

plate. Running at a lower voltage will damage the 

motor.
