YARDMAX YT4565 - Maintenance and Troubleshooting; Clutch Adjustment and Component Replacement

Never use a “pressure washer” to clean your unit.
Water can penetrate tight areas of the machine and
its transmission case and cause damage to spindles,
gears, bearings, or the engine. The use of pressure
washers will result in shortened life and reduce
serviceability.
GEARBOX
The gearbox was lled with lubricant to the proper level at the
factory. Unless there is evidence of leakage or service has been
performed on the gearbox, no additional lubricant should be
required.
GENERAL LUBRICATION
Lightly lubricate all moving parts of the machine at the end of the
season or every 25 operating hours.
MAINTENANCE
Maintaining your YARDMAX rear tine tiller will ensure long life to
the machine and its components.
PREVENTIVE MAINTENANCE
1. Turn off the engine and disengage all command levers. The
engine must be cool.
2. Keep the engine’s throttle lever in its SLOW position and
remove the spark plug wire from the spark plug and secure.
3. Inspect the general condition of the rear tine tiller. Check
for loose screws, misalignment or binding of moving parts,
cracked or broken parts, and any other condition that may
affect its safe operation.
4. Use a soft brush, vacuum or compressed air to remove all
contaminants from the machine. Then use high quality light oil
to lubricate all moving parts.
5. Replace the spark plug wire.

ADJUSTING CLUTCH
If clutch becomes difcult to engage follow these
steps to adjust the cable tension.
1. Loosen the jam nut by turning it counter clockwise with
8mm wrench while holding the adjustment nut in place
with 6mm wrench. (see Figure 10, Illustration 1)
2. Tighten (or loosen) the cable by turning the cable
adjustment nut clockwise (or counter clockwise) with
a 6mm wrench until you have reached your desired
tightness. (see Figure 10, Illustration 2)
3. Once you have reached your desired cable tightness,
tighten the jam nut by turning it clockwise until it is
tight. (see Figure 10 Illustration 3)
IDLE SPEED
Set the throttle control lever to the SLOW position to reduce
stress on the engine when work is not being performed. Lowering
the engine speed will help extend the life of the engine, as well as
conserve fuel and reduce noise level.
STOP ENGINE
To stop the engine in an emergency, simply turn the engine switch
to the OFF position. Under normal conditions, use the following
procedure:
1. Move the throttle lever to the SLOW (
) position.
2. Let the engine idle for one or two minutes.
3. Turn the engine switch to the OFF position.
4. Turn the fuel valve lever to the OFF (
) position.
Do not move the choke control to CLOSE to stop the
engine. Backre or engine damage may occur.
Sudden stopping at a high speed under a heavy load
is not recommended. Engine damage may result.
