c. Disconnect the plug from the power source before 

making any adjustments, changing accessories, or 

storing power tools.

 Such preventive safety measures 

reduce the risk of starting the power tool accidentally.

d. Store idle power tools out of the reach of children 

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.

e. Maintain power tools. Check for misalignment or 

binding of moving parts, breakage of parts and 

any other condition that may affect the power tools 

operation.

 If damaged, have the power tool repaired 

before use. Many accidents are caused by poorly 

maintained power tools.

f.  Keep cutting tools sharp and clean.

 Properly 

maintained cutting tools with sharp cutting edges are less 

likely to bind and are easier to control.

g. Use the power tool, accessories and tool bits etc., 

in accordance with these instructions and in the 

manner intended for the particular type of power 

tool, taking 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.

5. Battery tool use and care
a. Ensure the switch is in the off position before 

inserting battery pack.

 Inserting the battery pack into 

power tools that have the switch on invites accidents.

b. 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.

c. Use power tools only with specifically designated 

battery packs. 

Use of any other battery packs may 

create a risk of injury and fire.

d. 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 terminals together may cause burns 

or a fire.

e. Under abusive conditions, liquid may be ejected 

from the battery; avoid contact.

 If contact accidentally 

occurs, flush with water. If liquid contacts eyes, 

additionally seek medical help. Liquid ejected from the 

battery may cause irritation or burns.

6. Service
a. 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.

Additional safety instructions for drills

Wear ear protectors with impact drills.  

Exposure to noise can cause hearing loss.

Use auxiliary handles supplied with the tool. 

Loss of control can cause personal injury.

   If possible, always use clamps or a vice to hold your work.

   Always switch off before you put the drill down.

   Ensure that the lighting is adequate.

   Do not put pressure on the drill, such that it slows the 

motor down. Allow the drill bit to cut without pressure.  

You will get better results and you will be taking better 

care of your tool.

   Keep the area free of tripping hazards.

   Do not let anyone under 18 years operate this tool.

   Only use accessory bits in good condition.

   Before drilling, check that there is sufficient clearance for 

the drill bit under the workpiece.

   Do not touch the bit after operation. It will be very hot.

   Keep your hands away from under the workpiece.

   Never use your hands to remove sawdust, chips or waste 

close by the bit.

   Rags, cloths, cord, string and the like should never be left 

around the work area.
