ASSEMBLING THE BLOWER TUBES
See Figures 3 - 5.
 Place a large tube clamp onto the outer slot of the upper
(wider) end of the bellows.
 Attach upper end of bellows onto blower housing by
sliding it over the air outlet. The raised ridge closest to
the air outlet should securely fit into the slot inside the
bellows when the bellows is properly installed. Tighten
the large tube clamp using the assembly tool.
 Place a tube clamp on other end of bellows. Press bel-
lows onto throttle control handle tube. Tighten small tube
clamp using the assembly tool.
NOTE: The position of the throttle control handle may be
adjusted for comfort after the blower is strapped onto the
operator's back.
 Join the straight tube and nozzle together by aligning
raised locking tabs on straight tube with the raised lock-
ing slots on nozzle and twist until the tubes snap into the
locked position to secure.
WARNING:
Do not allow familiarity with this product to make you
careless. Remember that a careless fraction of a second is
sufficient to inflict serious injury.
ASSEMBLY
NOTICE:
When correctly assembled, the tubes are difficult to sepa-
rate. If they can easily be twisted apart, the tubes are not
locked. Continue twisting together until the tubes snap
into the locked position. Tubes that are not fully locked
together can separate during blower operation.
 Assemble the connected straight tube and nozzle to the
throttle control handle tube by aligning raised locking tabs
on the throttle control handle tube with the raised locking
slots on connected lower tubes by twisting to secure.
NOTE: Check all locking connections after initial run to
ensure they are tightly secured.
CAUTION:
Make all adjustments to the harness straps before start-
ing the blower to avoid the possibility of injury.
ADJUSTING HARNESS
See Figure 6.
Straps should be adjusted to a comfortable position before
starting the blower.
To adjust harness strap assembly:
 Blower should be in operating position before adjusting
the harness straps. Slip arm through harness strap and
onto shoulder, then repeat for the other shoulder.
 Grasp the lower adjustment strap and tighten (pull down
on strap) until the backpack blower rests comfortably
against the small of the back.
 Next, grasp the upper adjustment straps and tighten (pull
down on strap) until the backpack blower fits comfortably
on the shoulders.
 Once the blower feels comfortable, secure the chest
strap.
ADJUSTING THROTTLE CONTROL HANDLE
See Figure 7.
 Loosen locking screw by turning counterclockwise.
 Move throttle control handle to desired position and
secure locking screw by turning clockwise.
