Assembling the chain bar and chain (figs. G&H)

WARNING: Before chain or other adjustments, make sure that the battery is disconnected from the tool.

WARNING: Always wear protective gloves when installing or removing the saw chain. The saw chain is sharp and can cut you when it is not running.

-Ensure the operation is carried out on a firm surface.

-Open the handles and pull back the top jaw (1).

-Insert the chain bar into the space between the chain tensioner and align with the chain bar locator, angle the chain bar down ensuring it is correctly located.

-Place the chain (14) around the front of the chain bar and engage in the nose sprocket of the chain bar. Make sure chain is installed properly, with the cutting teeth facing forward as shown here.

Pull the chain bar and chain back, engaging it in the groove in the chain bar and then over the sprocket (15) positioning teeth in the correct position on the sprocket.

-Replace the chain access cover (13) and retention bolts (11) tightening securely.

Operation

Never operate a chain saw that is damaged or improperly adjusted or that is not completely and securely assembled. Be sure that the saw chain stops moving when the power control system triggers are released. Never adjust the guide bar or saw chain when the engine is operating.

WARNING: Let the tool work at its own pace. Do not overload.

-Carry out regular cleaning of the unit as described in the maintenance section and in particular cleaning inside the chain access cover.

-The lower guard jaw (2) and top jaw (1) are designed to close when one of the handles is released or when the piece of branch being cut has been cut. If this does not occur, discontinue use of the tool and remove the battery pack. Check if any debris is blocking movement. To help in this process it may be necessary to

remove chain access cover(13). If on assembly the problem is still present take the unit to a service center.

Oiling (fig. I)

A high quality bar and chain oil or SAE30 weight motor oil should be used for chain and bar lubrication. The use of a vegetable based bar and chain oil is recommended when pruning trees. Never use waste oil or very thick oil. These may damage your chain saw.

-Before first use and every ten minutes of use you must oil the product with the recommended chain oil. Open the oiling cover (4) and insert the bottle into the oil filling hole (16) apply pressure to the bottle once to dispense oil.

-This should be adequate for about 10 minutes of cutting depending upon cutting speed and type of wood.

-The hole feeds the oil through to the chain onto the chain bar and an excessive amount of oil applied to the unit could mean the oil drips from the unit around the jaw area. This is normal and is nothing to be concerned about.

Switching on and off (fig. J)

For your safety, this tool is equipped with a double switching system. This system prevents starting the tool inadvertently.

A chain saw is intended for two-handed use. Serious injury to the operator, helpers, and/or bystanders can result from one-handed operation.

Switching on (fig. K)

To open the handles, slide the latch (5) backwards and pull the handles apart. Ensure a firm grip on the handles and then squeeze both switch actuators to switch the unit on.

Note: Both switches must be activated for the product to be used. Do not force the tool - allow it to do the work. It will do a better and safer job at the speed for which it is designed. Excessive force will stretch the chain.

If the saw chain or bar becomes jammed:

-Switch the tool off.

-Remove the battery from the tool.

-Open the cut with wedges to relieve the strain on the guide bar. Do not try to wrench the saw free. Start a fresh cut.
