Check For Debris - Toro 73547 Wheel Horse 520Lxi Operator's Manual

Check for Debris

IMPORTANT: Operating the engine with a
blocked grass screen and/or cooling shrouds
removed, will result in engine damage from
overheating.
1. Park the machine on a level surface, disengage
the power take off (PTO), set the parking brake,
lower the attachment lift, and turn the ignition
key to "STOP" to stop the engine. Remove the
ignition key.
2. Check for debris on the (3) air intake screens
(Fig. 7). Wipe away debris before each use
and/or during use, if required.

3. The radiator screen (Fig. 8) is located between
the radiator and the dash in the tractor. To
remove it, pull it up from its retention slot.
Wipe or wash off all accumulated debris from
the screen, then reinstall it.
4. In dry or dusty conditions, dust can build up on
the radiator fins and reduce cooling efficiency.
Remove the radiator screen and blow (or low
pressure wash) the radiator cooling fins.

Debris can build up in the engine area. Clean
any debris build–up with a brush or blower
before each use.
IMPORTANT: It is preferable to blow dirt
out (Fig. 9), rather than washing it out. If
water is used, keep it away from electrical
items.

IMPORTANT: DO NOT HIGH–PRESSURE
WASH. High–pressure washing can damage
the electrical system or deplete grease.
