Maintenance Instructions

Cleaning

GHS Blower

Normally, the GHS blower operates with no

mainte nance or cleaning. However, when mowing

grass that is dirty and damp

(especially certain

springtime mow ing conditions), a deposit of dirt

may accumulate inside the blower housing, caus-

ing wear and binding of the blower wheel. When

operating in these conditions,

inspect the blower

frequently for dirt buildup.
NOTE:

A visual clue of binding of the blower wheel

is the blower

blade tips are polished

from rubbing

on dirt.

When a dirt deposit is found, use a high pressure

washer or water spray to clean the inside of the

housing as follows:

DANGER

Before attempting to wash the blower,

stop the engine, remove the ignition key,

and disconnect the spark plug wires.

Wear goggles or face shield.

1. Disconnect blower from driveline by removing

(1) mower deck, (2) PTO Coupler [quick dis-

connect], (3) Engine Belt, and (4) PTO Drive

belt. These parts are removed to allow free

movement of the blower wheel.

IMPORTANT:

With the driveline disconnect-

ed, the blow er wheel

must spin freely.

Any

binding or drag ging of the wheel is an indica-

tion of dirt buildup. This

buildup must be

cleaned

to avoid abrasive wear of the blower

blades, ex cessive power loss and eventual

loss of blower performance (clogging).

2. Use a pressure washer or water spray, and

di rect the spray inside the blower housing

against the blower blades. Water pressure will

cause the blower wheel to begin to spin and

the com bination of spinning action and water

will effec tively wash the inside of the housing.

Spray may be directed against the blower

blades ver tically and horizontally to cause

rotation in both directions for thorough wash-

ing action.

Wash blower until the blower

wheel spins freely

in both directions.

Reconnect the GHS Blower Driveline by re-

versing the removal procedure.

Transaxle Housing

Keeping the housing on the transaxles clean and

free of obstruction is

essential to avoid overheat-

ing

the transaxle fluid and shortening transaxle

life. The housing should be checked

every 100

hours

and cleaned if necessary.

To clean the housing, use compressed air and/or a

pressure washer. Pay close attention to any oily

dirt buildup on the transaxle housings. This may

be the result of an oil leak. If an oil leak is noticed,

contact your local Walker dealer.

Cooling

Fins

Transaxle Housing and Cooling Fins

IMPORTANT:

In case an oil leak develops on the

input shaft, the cooling fan blowing dusty air and oil

on the transaxle will

quickly

cover the housing and

pack the cooling fins with

oily dirt.

If this condition

occurs, contact your dealer immediately to avoid

overheating and dam aging the transaxle.

An additional procedure in maintaining transaxle

cooling is to inspect the cooling fans. Replace the

fan(s) if blades are missing or damaged.
