Power tool use and care

1. 

Do not force the power tool. Use the correct 

power tool for your application.

 The correct 

power tool will do the job better and safer at the 

rate for which it was designed.

2. 

Do not use the power tool if the switch does 

not turn it on and off.

 Any power tool that cannot 

be controlled with the switch is dangerous and 

must be repaired.

3. 

Disconnect the plug from the power source 

and/or the battery pack from the power tool 

before making any adjustments, changing 

accessories, or storing power tools.

 Such pre-

ventive safety measures reduce the risk of starting 

the power tool accidentally.

4. 

Store idle power tools out of the reach of chil-

dren and do not allow persons unfamiliar with 

the power tool or these instructions to operate 

the power tool.

 Power tools are dangerous in the 

hands of untrained users.

5. 

Maintain power tools. Check for misalignment 

or binding of moving parts, breakage of parts 

and any other condition that may affect the 

power tool’s operation. If damaged, have the 

power tool repaired before use.

 Many accidents 

are caused by poorly maintained power tools.

6. 

Keep cutting tools sharp and clean.

 Properly 

maintained cutting tools with sharp cutting edges 

are less likely to bind and are easier to control.

7. 

Use the power tool, accessories and tool bits 

etc. in accordance with these instructions, tak-

ing into account the working conditions and 

the work to be performed.

 Use of the power tool 

for operations different from those intended could 

result in a hazardous situation.

Battery tool use and care

1. 

Recharge only with the charger specified by 

the manufacturer.

 A charger that is suitable for 

one type of battery pack may create a risk of fire 

when used with another battery pack.

2. 

Use power tools only with specifically desig

-

nated battery packs.

 Use of any other battery 

packs may create a risk of injury and fire.

3. 

When battery pack is not in use, keep it away 

from other metal objects, like paper clips, 

coins, keys, nails, screws or other small metal 

objects, that can make a connection from one 

terminal to another.

 Shorting the battery termi

-

nals together may cause burns or a fire.

4. 

Under abusive conditions, liquid may be 

ejected from the battery; avoid contact. If con-

tact accidentally occurs, flush with water. If 

liquid contacts eyes, additionally seek medical 

help.

 Liquid ejected from the battery may cause 

irritation or burns.

Service

1. 

Have your power tool serviced by a qualified 

repair person using only identical replacement 

parts.

 This will ensure that the safety of the power 

tool is maintained.

2. 

Follow instruction for lubricating and chang-

ing accessories.

3. 

Keep handles dry, clean and free from oil and 

grease.

Cordless grinder safety warnings

Safety Warnings Common for Grinding, Sanding, 

Wire Brushing, or Abrasive Cutting-Off Operations:

1. 

This power tool is intended to function as a 

grinder, sander, wire brush or cut-off tool. 

Read all safety warnings, instructions, illus-

trations and specifications provided with this 

power tool.

 Failure to follow all instructions listed 

below may result in electric shock, fire and/or 

serious injury.

2. 

Operations such as polishing are not rec-

ommended to be performed with this power 

tool.

 Operations for which the power tool was not 

designed may create a hazard and cause per

-

sonal injury.

3. 

Do not use accessories which are not specifi

-

cally designed and recommended by the tool 

manufacturer.

 Just because the accessory can 

be attached to your power tool, it does not assure 

safe operation.

4. 

The rated speed of the accessory must be at 

least equal to the maximum speed marked on 

the power tool.

 Accessories running faster than 

their rated speed can break and fly apart.

5. 

The outside diameter and the thickness of your 

accessory must be within the capacity rating 

of your power tool.

 Incorrectly sized accessories 

cannot be adequately guarded or controlled.

6. 

Threaded mounting of accessories must 

match the grinder spindle thread. For acces-

sories mounted by flanges, the arbour hole of 

the accessory must fit the locating diameter 

of the flange.

 Accessories that do not match the 

mounting hardware of the power tool will run out of 

balance, vibrate excessively and may cause loss 

of control.

7. 

Do not use a damaged accessory. Before each 

use inspect the accessory such as abrasive 

wheels for chips and cracks, backing pad for 

cracks, tear or excess wear, wire brush for 

loose or cracked wires. If power tool or acces-

sory is dropped, inspect for damage or install 

an undamaged accessory. After inspecting and 

installing an accessory, position yourself and 

bystanders away from the plane of the rotating 

accessory and run the power tool at maximum 

no-load speed for one minute.

 Damaged acces-

sories will normally break apart during this test 

time.

8. 

Wear personal protective equipment. 

Depending on application, use face shield, 

safety goggles or safety glasses. As appro-

priate, wear dust mask, hearing protectors, 

gloves and workshop apron capable of stop-

ping small abrasive or workpiece fragments.

 

The eye protection must be capable of stopping 

flying debris generated by various operations. 

The dust mask or respirator must be capable of 

filtrating particles generated by your operation. 

Prolonged exposure to high intensity noise may 

cause hearing loss.

9. 

Keep bystanders a safe distance away from 

work area. Anyone entering the work area 

must wear personal protective equipment.
