Anti-vibration System

MAKITA has developed a particularly

effective system for damping engine

vibrations: the MAKITA twin-mass

system known as D2M. The vibrating

mass, consisting of the engine and

sawing mechanism, is isolated from the

other parts of the chainsaw by vibration

damper elements. The damping mass is

thus greater, and – in accordance with

the physical law of inertia – more effecti-

ve than simply damping the handles as

such. Scientific measurements carried

out by various test institutes have confir-

med the remarkable effectiveness of the

D2M system. Effective vibration damping

reduces the physical stress of working

with a chainsaw. The hands remain stea-

dy when sawing, and the blade can be

guided safely and accurately.

SafetyMatic chain brake

All MAKITA chainsaws have one particu-

larly important safety feature: a chain

brake that can be operated manually or

activated by inertia. On some electric

chainsaw models it incorporates an addi-

tional micro-switch, which simultaneously

cuts the power to the motor. The

SafetyMatic feature ensures that the saw

chain comes to a complete stop in a frac-

tion of a second.

BIOTOP saw chain oil

With the development of its BIOTOP

chain oil MAKITA has effectively elimi-

nated any adverse environmental

impact associated with the lubrication

of saw chains. BIOTOP is plant-based

and biodegrades very quickly.

Reduced emissions

The petrol engines fitted to all MAKITA

chainsaws, grass trimmers, brushcut-

ters and disc cutters are designed to

run on lead-free petrol. So the environ-

ment is not polluted by harmful lead

emissions.

To make up the 2-stroke mixture we

recommend the use of Extra HP-100 2-

stroke motor oil for all MAKITA chain-

saws. This high-performance synthetic

oil is suitable for all mix ratios up to 1 :

100. It is up to 90% biodegradable, and

delivers excellent lubrication performan-

ce with very low exhaust gas emissions.

2-stroke engine oil

Any conventional high-performance 2-

stroke engine oil can be used in

power tools designed to run on a 1 :

40 mixture. However, in order to mini-

mize emissions we recommend the

use of MAKITA’s 1 : 50 high-perfor-

mance oil. Best of all for the environ-

ment, of course, is MAKITA's HP-100

motor oil, which is used in a mix ratio

of 1 : 100 to reduce environmental

pollution to an absolute minimum.

KEY TECHNICAL FEATURES

Two-hand safety operation

All MAKITA electric hedge trimmers incor-

porate a two-hand safety operation featu-

re. This offers optimum protection against

injury because the machine can only be

operated with both hands firmly gripping

the handle switches. If either of these swit-

ches is released, the blades come to a

complete stop in a fraction of a second.

Both handles are generously sized to per-

mit comfortable working with gloves. The

new generation of professional hedge trim-

mers, with four safety handles for greatly

extended reach, feature 4-point switching.

Electrically heated handles

Chainsaw models with an “H” suffix in the

type number come with a built-in handle

heating system. This keep hands warm

and gloves dry in cold weather and helps

to prevent circulatory problems.

MAKITA SAFETY FEATURES

Noise prevention:

legal requirements

An important consideration in the

development of power tools for the

garden is the need to minimize opera-

ting noise in order to protect the user,

the neighbours and the environment in

general. In May 2002 Germany signed

up to EU Directive 2000/14/EC, whe-

reby all new power tools have to be

put through a series of elaborate

acoustic tests by the manufacturer.

The peak noise level, measured in

dBA, must be clearly marked on every

machine sold.
