Vibration

The vibration total value (tri-axial vector sum) deter-

mined according to EN60745:

Work mode: impact tightening of fasteners of the maxi

-

mum capacity of the tool

Vibration emission (a

h

) : 2.5 m/s

2

Uncertainty (K) : 1.5 m/s

2

NOTE:

 The declared vibration emission value has 

been measured in accordance with the standard test 

method and may be used for comparing one tool with 

another.

NOTE:

 The declared vibration emission value 

may also be used in a preliminary assessment of 

exposure.

WARNING:

 The vibration emission during actual 

use of the power tool can differ from the declared 

emission value depending on the ways in which the 

tool is used.

WARNING:

 Be sure to identify safety measures 

to protect the operator that are based on an estima-

tion of exposure in the actual conditions of use (taking 

account of all parts of the operating cycle such as the 

times when the tool is switched off and when it is run-

ning idle in addition to the trigger time).

EC Declaration of Conformity

For European countries only

The EC declaration of conformity is included as Annex A 

to this instruction manual.

IMPORTANT SAFETY 

INSTRUCTIONS

• 

The “important safety instructions” described 

below should always be followed to reduce the 

risk of a fire, electric shock, and personal injury.

• 

Before operating the machine, read and carefully 

follow these instructions.

• 

This manual should be retained for future 

reference.

 

WARNING

1.  Before use, read this Instruction Manual 

thoroughly.

2.  Use only the charger and battery specified in 

this Instruction Manual.

· 

Any combination, except that specified in this 

manual, may cause injury or damage due to 

explosion.

3.  Charge properly.

· 

Use this charger only with the rated AC power 

supply. Do not use booster transformers or vehicle 

generator, or use the charger to supply DC power. 

Incorrect use may cause overheating and fire.

· 

Do not charge the battery at a temperature under 

10°C (50°F) or more than 40°C (104°F) as this 

may cause an explosion or fire.

4. 

Do not short-circuit the pins of the battery. 

Avoid storing battery in a container with other 

metal objects such as nails, coins, etc. This 

may cause overheating, fire and explosion due 

to short-circuit.

5.  Guard against an electric shock.

· 

Do not touch the power plug with a wet or damp 

hands as this may result in an electric shock.

6.  Consider the work area environment.

· 

Do not expose the charger and battery to rain or 

use them in damp or wet locations, as this may 

cause overheating or electric shock.

· 

Keep the work area well lighted. Working where 

there is insufficient light may cause an accident.

· 

Do not use or charge the battery where there are 

flammable fluids or gases, as this may cause 

explosion or fire.

7.  Wear Safety Glasses and Protective Clothing

· 

Always wear eye protection, dust mask, non-skid 

safety shoes, helmet and any other mandated 

or necessary protective clothing while using this 

equipment. Failure to do so may result in injury.

8.  Prevent unintentional starting.

· 

Ensure the switch is in the off-position before con-

necting to power source and/or battery pack, pick-

ing up or carrying the tool. Carrying power tools 

with your finger on the switch invites accidents.

9.  Secure the work.

· 

Use clamps or a vice to hold the work. This frees 

both hands to properly hold, control, and operate 

the tool. Failure to properly secure the work may 

result in injury.

10.  Disconnect the tools power supply, by remov-

ing the Battery and engaging the Trigger 

Switch Lock, whenever one of the following 

situations occur.

· 

The tool is not in use or is being serviced.

· 

Any parts, such as a blade, are being replaced.

· 

There is a recognised hazard.

 

Failure to do so may result in accidental operation 

and damage or injury.

11.  Only use the specified accessories or 

attachments.

· 

Use only the accessories or attachments 

described in this Instruction Manual and the 

Makita catalog. Use of any other accessories or 

attachments may result in an accident or injury.

12.  Do not expose the battery to fire as it may 

explode or generate poisonous substances.

13.  Under conditions of abuse, liquid may be 

ejected from the battery; avoid contact.

· 

If contact accidentally occurs, flush with clear 

water.

· 

If liquid contacts eyes, flush with clear water and 

seek immediate medical help as it may result in 

loss of eyesight.

14.  If operating time has reduced very signifi

-

cantly, stop operating immediately. There is a 

risk of overheating which may result in burns 

and even an explosion.
