Craftsman 71.74291 operating instructions Adjusting SAW Chain Tension, Oiling the Chain

Figure 4

Rotate the socket head screw on the front of the saw head clockwise to take up the slack in the chain. (see figure 2 from previous step)

Replace the sprocket cover, bar clamp and socket head screws in that order.

Adjust the tension on the chain before use.

ADJUSTING SAW CHAIN TENSION

With the battery removed from the power handle, pull the center of the chain away from the bar at the center of the bar with your fingers (always wear gloves). The tension is correct when you can pull the chain 1/8” from the bar and it snaps back when released. (see figure 5) The chain should not sag away from the bar.

Figure 5

To adjust the chain tension, loosen the socket head screw that hold the bar clamp.

Turn the socket head screw on the

front of the saw head to loosen or tighten the chain as needed. When the chain is the correct tension, tighten the two socket head screws that hold the bar clamp in place.

Do not over-tighten the chain as this will lead to premature wear of the chain and bar. Over-tightening can also reduce battery life and cause the circuit breaker to trip.

Check the tension on the chain often when it is new. New chain stretches in the initial few hours of use.

OILING THE CHAIN

Oil the chain before each use with unused SAE30 weight motor oil or saw chain oil. Lubricate the chain along its entire length.

CONNECTING POLE SAW ATTACHMENT TO THE POWER HANDLE
