B. Slide the spring cover of f the spring and the cable
adjuster.
C.
Unhook the Z fitting from the cable adjuster and
reposition the Z fitting in a higher or lower hole on
the adjuster to obtain a proper gap of 1/16 to 1/8 in.
(0.16 to 0.32 cm) between the control bar bracket
and the handle (Fig. 1 1).
D.
Install the spring cover over the cable adjuster and
the spring.
E. Hook the spring into the top hole of the control bar
bracket (Fig. 10).
Models 38441 and 38442 only:
A. Unhook the upper cable end from the hole in the
control bar bracket (Fig. 10).
B. Slide the spring cover up the cable to expose the
cable adjuster (Fig. 10).
C. Unhook the Z fitting from the cable adjuster and
position it in a higher or lower hole on adjuster to
obtain a gap of 1/16 to 1/8 in. (0.16 to 0.32 cm)
between the control bar bracket and the handle
(Fig. 1 1).
D.
Install the spring cover over the cable adjuster .

5. Check the adjustment (refer to steps 2 and 3 above).
After extended use, the drive belt may wear and lose its
proper belt tension. Improper belt tension causes belt
slippage and decreases the performance under a heavy
load. Belt slippage may occur after two or three seasons of
normal usage (10 to 15 hours). If the drive belt slips
(continuously squeals) under a heavy load, increase the
belt tension by doing one of the following steps:
• For Models 38428 and 38429: Reposition the spring
end in the bottom hole of the control bar bracket
(Fig. 10).
• For Models 38441 and 38442: Reposition the upper
cable end into the upper hole of the control bar bracket
(Fig. 12).
Using the incorrect adjusting hole in the control bar
bracket unnecessarily can reduce the drive belt life.
Occasional belt slippage (squealing) may occur in
extremely wet conditions due to moisture in the drive
system. T o remove moisture, start the rotor and operate it
without a load for 30 seconds. Once you remove the
moisture, the drive belt should not slip.
Emptying the Fuel T ank
1. Stop the engine and remove the key from the switch.
2. Remove the fuel tank cap and use a pump-type syphon
to drain the fuel into a clean gasoline container .
3.
Start the engine and allow it to run until it consumes
all the fuel in the fuel tank and stops running. Repeat
this step two more times to remove all the fuel in the
fuel tank and the carburetor .
Replacing the Scraper
Before each season, inspect the scraper for wear . If the
thickness of the scraper ’ s bottom is less than 1/16 in.
(0.16 cm), replace the scraper (Fig. 18).

Note: The running time and the roughness of the driveway
or sidewalk determines the scraper wear rate.
1. Stop the engine.
2. Drain the fuel from the fuel tank. Refer to Emptying
the Fuel T ank on page 17.
3. T ip the snowthrower forward onto its front housing.
4. Remove three carriage bolts and the locknuts holding
scraper in place (Fig. 19).
5. Remove the scraper by sliding it to the right and down.
