Intended Use; Preparation - Qualcast QHTLi40 Instruction Manual

Intended Use

The chainsaw is intended for sawing trees, tree trunks, branches, wooden beams,
and planks, etc. Cuts can be sawn with or across the grain. This product is not
suitable for sawing mineral materials.

Preparation

Tensioning chain
Always check the chain tension before use, after the first cuts and regularly
during use, approx. every 10 minutes. Upon initial operation, new chains can
lengthen considerably.
WARNING: Unplug the chainsaw from the power source before adjusting
the saw chain tension.
WARNING: Cutting edges on the chain are sharp. Use protective gloves
when handling the chain.
WARNING: Maintain proper chain tension always. A loose chain will
increase the risk of kickback. A loose chain may jump out of the guide
bar groove. This may injure the operator and damage the chain. A loose
chain will cause the chain, chain bar, and sprocket to wear rapidly.
The chain life of the saw chain mainly depends upon sufficient lubrication and
correct tensioning.
Avoid tensioning the chain if it is hot, as this will cause the chain to become
over tensioned when it cools down.
Please note that the chain tension has already been adjusted ready for use, but be
sure to double check if the chain tension is correct. If the chain tension is incorrect,
tighten or loosen the chain and bar to the best position. The machine can be used
only on the condition that the chain tension is correct and the bar is fixed for safety.
The correct chain tension is reached when the chain (8) can be raised approx. 2-3mm
from the chain bar in the centre. This should be done by using one hand in a glove to
raise the chain against the weight of the machine. (See Fig. F).
In case of a too tight chain and bar, please make the below action:
1. Loosen the chain bar by turning the chain locking knob (11) anticlockwise until it is
slightly loose (usually half or one cycle away). (See Fig. F).
2. Loosen the chain tensioning knob (12) anticlockwise a little every time to check the
chain tension until it is correct.
3. When the chain tension is correct, please fix the position of the chain tensioning
knob (12) by one hand while turning back the chain locking knob (11) clockwise by
another hand to the end.
