Original Instructions
GETTING STARTED
See page 190 - 192.
1. Wear Personal Protective Equipment (PPE).
Wear full eye protection, ear protection, non-slip heavy-
duty gloves, substantial footwear, and protective clothing
at all times while operating the product. Do not operate
the product when barefoot or wearing open sandals.
2. Loosen the sprocket cover screw and remove the
sprocket cover.
3. Place the chain drive links into the bar groove. Position
the chain so that there is a loop at the back of the bar.
The saw chain should face in the direction of chain
rotation. If the chain faces backwards, turn the loop over.
4. Hold the chain in position on the bar, and place the loop
around the drive sprocket. Lower the bar so that the bolt
goes through the slot in the bar. Rotate the assembly so
that the bolt and hole align.
5. Replace the sprocket cover and tighten the sprocket
cover screw.
6. Adjust the chain tension. Turn the chain tensioning
screw using the combination wrench. Frequently check
the chain tension while adjusting.
–
To increase the chain tension, turn the chain
tensioning screw clockwise.
–
To reduce the chain tension, turn the chain tensioning
screw counterclockwise.
NOTE: The chain tension is correct when the gap
between the cutter in the chain and the bar is between
2.5 and 3.5 mm. Pull the chain in the middle of the lower
side of the bar downwards (away from the bar), and
measure the distance between the bar and the chain
cutters.
NOTE: The temperature of the chain increases during
normal operation, causing the chain to stretch. Check
the chain tension frequently and adjust as required. A
chain that is tensioned while warm may be too tight upon
cooling. Make sure that the chain tension is correctly
adjusted as specified in these instructions.
7. Install the battery pack.
Align the raised ribs on the battery pack with the grooves
in the product’s battery port. Insert the battery pack into
the product. Make sure that the latch of the battery pack
clicks in place and that the battery pack is fully seated
and securely attached before beginning operation.
WARNING! Grip both handles with the thumbs and
fi ngers encircling the handles. Ensure that the left hand is
holding the front handle so that the thumb is underneath.
WARNING! Always hold the product with the right hand
on the rear handle and the left hand on the front handle.
8. Start the product.
Pull the trigger release, and squeeze the switch trigger.
