ATTACHING EXTENSION CORD
1. Remove Plug safety cap as shown (Fig. 7a). Insert extension cord socket into
Chain Saw's 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.
