Air flow test
1. Disconnect the air hose from the blower.
2. Attach the air flow indicator to the unit.
3. Turn on the blower. If the blower unit does not provide at least 160
lpm of air, ensure the use of clean pre-filters and filters and a fully
charged battery and re-try. If the problem persists, follow the
troubleshooting instructions or contact the manufacturer.
Troubleshooting
Belt
The waist belt holds the blower unit to the lower back. The buckles snap
together. The buckles are released by squeezing the top and bottom of
buckle.
DO NOT POSITION THE BLOWER UNIT ON THE FRONT OF THE BODY
OR WHERE IT CAN BE EXPOSED TO SPARKS.
Belt Adjustment
1. Adjust the length of the belt by sliding the belt through the
buckles to reach the desired length.
2. Adjust the elastic keepers to secure the loose tails of
the belt.
Belt Removal and Replacement
1. To remove the belt from the blower, depress the plastic
tabs on the inside of the belt near the blower unit to release
the belt attachment clips from the blower unit.
2. To attach the belt to the blower, snap the attachment clips
onto the rails on the blower. Note that there is a left and right side to
the belt and clips will only attach when correctly aligned.
