Chain Saw WG303E
CUTTING
- is the oil reservoir filled? Check oil level gauge (19) 
prior to starting and regularly during operation. Refill 
oil when oil level is low. The oil tank filling will last 
approx. 16minutes, depending on sawing intensity 
and stops. (See Fig. H)
- is the chain tension in order and is the chain sharp? 
Check new replaced chain tension approx. every 10 
minutes during operation. Upon initial operation, 
new chains can lengthen considerably. The condition 
of the chain influences the cutting performance. Only 
a sharp chain protects from overload. 
- is the kickback deactivated and its function ensured?
- are you wearing the necessary protective equipment? 
Wear safety glasses /goggles/visor –safety helmet 
and hearing protection. Further protective equipment 
for head, hand, legs and feet is highly recommended. 
Adequate protective clothing will reduce personal 
injury by flying debris or accidental contact with saw 
chain.
Proper functioning of the automatic oiler can be checked 
by running the chain saw and pointing the tip of the 
chain bar towards a piece of cardboard or paper on 
the ground. Caution: Do not touch the ground with the 
chain. Ensure safety clearance of 20 cm. If an increasing 
oil pattern developes, the automatic
oiler is operating fine. If there is no oil pattern, despite 
a full oil reservoir, see “Troubleshooting” or contact 
WORX customer service agent or approved service 
agent.
Kickback (See Fig. G)
Kickback is the sudden backward/upward motion of the 
chain saw, occurring when the chain (at the tip of the 
chain bar) comes in contact with a log or wood, or when 
the chain becomes jammed.
When kickback occurs the chainsaw reacts unpredictably 
and can cause severe injuries to the operator or 
bystanders.
Particular attention must be given when sawing 
sideward, slanted or during length cuts, as the spiked 
bumper usually can not be applied.
To avoid kickback:
- saw with guide bar at a flat angle.
- never work with a loose, widely stretched or the 
heavily worn out chain.
- ensure chain is sharpened correctly.
- never saw above shoulder height.
- never work with the tip of the guide bar.
- always hold the chain saw firmly with both hands.
- always use a low kickback chain.
- apply the metal gripping teeth for leverage.
- ensure correct chain tension.
