OPERATION

ATTACHING EXTENSION CORD
1. Remove Plug safety cap as shown (Fig. 7a ). Insert extension cord socket into
Chain Saw Plug (Fig. 7b).
2. An Extension Cord Retainer is attached to the Handle to reduce strain on the cord.
To use this feature, simply double the extension cord as shown, about a foot from
the end, and insert it into the end of the Retainer. Place the loop formed by
doubling the cord over the Hook (Fig. 7c). Gently tug on the cord to ensure that it
is firmly situated in the Retainer (Fig. 7d).
3. Keep extension cord clear of operator, unit and any obstacles at all times.
Do not expose the cord to heat, oil, water, or sharp edges.

CUTTING
Check oil level gauge prior to starting and regularly during operation. Refill oil when oil level is

low. The oil tank filling will last approximately 16 minutes, depending on sawing intensity and
stops. (See Fig. 6 on page 18)
Confirm the chain tension is in working order and the chain sharp.
Pause operation to check tension of a new replacement chain.
See TENSIONING CHAIN instructions.
Upon initial operation, new chains can lengthen considerably. The condition of the chain
influences the cutting performance. Only a sharp chain protects from overload which can
result in jamming and kickback.
Make sure you are wearing the necessary protective equipment.
Wear safety glasses/goggles /visor – safety helmet and hearing protection.
Further protective equipment for head, hands, legs and feet is highly recommended.
Adequate protective clothing will reduce personal injury by flying debris or accidental
contact with saw chain.
