Safety features

1.Always check that the safety features are in working order before starting work. Do not use the chain saw if the safety features are not working properly.

Chain brake:

 

 

The chain saw is fitted with a chain brake which

 

brings the saw chain to a standstill within a fraction

 

of a second. It is activated when the hand guard is

 

pushed forwards. The saw chain then stops within

 

0.15 s, and the power supply to the motor is

 

interrupted.

Run-down brake:

The chain saw is equipped with an run down brake which brings the saw chain to an immediate stop when the ON/OFF switch is released. This prevents the saw chain from running on when switched off, and thus presenting a hazard.

The front and rear hand guards protect the user against injury from pieces of wood which may be thrown backwards, or a broken saw chain.

The trigger lockout prevents the chain saw from being switched on accidentally.

The chain catcher protects the user against injury should the chain jump or break.

Transport and storage

When the chain saw is not in use or is being transported, withdraw the mains plug and fit the guide bar cover supplied with the saw. Never carry or transport the saw with the saw chain running.

1.Carry the chain saw by the front handle only, with the bar pointing backwards.

2.Keep the chain saw in a secure, dry and locked room out of the reach of children. Do not store the chain saw outdoors.

Maintenance

1.Withdraw the plug from the socket before carrying out any adjustments or maintenance.

2.Check the power cable regularly for damage to the insulation.

3.Clean the chain saw regularly.

4.Have any damage to the plastic housing repaired properly and immediately.

5.Do not use the saw if the switch trigger is not working properly. Have it properly repaired.

6.Under no circumstances should any modifications be made to the chain saw. Your safety is at risk.

7.Do not carry out maintenance or repair work other than that described in this instruction manual. Any other work must be carried out by authorized service centers.

8.Only use genuine replacement parts and accessories intended for your model of saw. The use of other parts increases the risk of accident.

9.We accept no responsibility for accidents or damage should non-approved bars, saw chains or other replacement parts or accessories be used.
