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.
