Adjusting The Control Cable; Emptying The Fuel Tank; Replacing The Scraper - Toro CCR Powerlite 38173 Operator's Manual

POTENTIAL HAZARD
If you leave the wire on the spark plug, someone could start the engine.
WHAT CAN HAPPEN
Accidental starting of engine could seriously injure you or other bystanders.
HOW TO AVOID THE HAZARD
Pull the wire off of the spark plug before you do any maintenance. Also, push it aside so it
does not accidentally contact the spark plug.

Adjusting the Control Cable

Periodically check the control cable for proper
adjustment.
1. Stop the engine and wait for all moving parts to stop.
2. Move the control bar back toward the handle to
remove the slack in the cable (Fig. 4).
3. Ensure that a 1/16 to 1/8 in. (0.16 to 0.32 cm) gap
exists between the control bar and the handle (Refer to
the inset in Fig. 4). To adjust the cable, go to step 4.
Note: The control cable must have slack in the
disengaged position.
4. Unhook the spring end from the top hole in the control
bar bracket (Fig. 4).
5. Slide the spring cover off the spring and the cable
adjuster.
6. Unhook the Z fitting from the cable adjuster and
reposition the Z fitting in the top or bottom 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. 5).
7. Install the spring cover over the cable adjuster and the
spring.
8. Hook the spring into the top hole of the control bar
bracket (Fig. 4).
9. 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 repositioning the spring end in the bottom
hole of the control bar bracket (Fig. 4).
Using the incorrect adjusting hole in the control bar
bracket can reduce the drive belt life. Occasional belt
slippage (squealing) may occur in extremely wet
conditions due to moisture in the drive system. To remove
CAUTION
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 Tank

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 and approved gasoline
container.
3. Start the engine and allow it to run until all the engine
consumes all the fuel in the fuel tank and the engine
stops. Repeat this step two more times to remove all
the fuel in both 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.
(1.6 mm), replace the scraper (Fig. 10).
1. Stop the engine and remove the key from the switch.
2. Pull the wire off the spark plug.
3. Remove the three screws holding the scraper in place.
1. Scraper
4. Remove the scraper.
5. Secure the new scraper to the housing with the three
screws.
