Chain saw 

WG305E

14

NOTE: 

The Chain (10) will stretch while cutting and 

lose proper tension. When the chain becomes loose, 
completely unscrew the Chain Tensioning Knob (11) 
or turn the knob around three full turns in a counter-
clockwise direction, then retighten the Chain Tensioning 
Knob (11) to properly reset the chain tension by repeating 
Steps 1-4 listed above.

LUBRICATION

IMPORTANT: The chain saw is not filled with 

oil. It is essential to fill with oil before use. 

Never operate the chain saw without chain oil 

or at an empty oil tank level, as this will result in 

extensive damage to the product.

Filling oil tank:

WARNING:

 

Unplug chain saw from power 

source before filling the oil tank.

1.   Set chain saw on any suitable surface with Oil Filler 

Cap (5) facing upward.

2.   Clean area around the Oil Filler Cap with cloth and 

unscrew the cap by turning it counter clockwise.

3.   Add bar and chain oil until tank is full.
4.   Avoid dirt or debris entering oil tank, refit Oil Filler 

Cap (5) and tighten by turning clockwise until hand 
tight.

IMPORTANT: To allow venting of the oil 

tank, small breather channels are provided 

between the Oil Filler Cap and the strainer, to 

prevent leakage, and ensure machine is left in a 

horizontal position (Oil Filler Cap (5) uppermost) 

when not in use.

It is important to use only the recommended 

standard bar and chain oil (Grade: ISO VG32) to 

avoid damage to the chain saw. This can be found 

at the location where you purchased this saw or 

your local hardware store. Never use recycled/old 

oil. Use of non approved oil will void the warranty.

Oiling chain

Always check oil level before using saw. Do not attempt 
to operate the oil system while saw is in operation. To oil 
chain, press Bulb (23). Oil will feed through the Oil Outlet 
(17) onto the Guide Bar (9) and chain. Press Bulb (23) on 
Oil Filler Cap at least once before each cut (See Fig. F).
