HYDRAULIC RESERVOIR
CHECK, DRAIN AND FILL
Check level every 100 hours or when a leak has
occured. To check level: Remove reservoir cap. Add
10W30 oil until the oil level reaches the bottom of the
filler tube. Do not overfill.
EVERY 500 HOURS:
Change hydraulic oil and filter. Remove plug (D) to
drain reservoir. Remove and replace filter. Filter is
located on front of tank at (G). Reinstall plug and fill
with 10W30 oil to the bottom of the filler tube (F).
NOTES:
• When any fuel pipe orifice is left opened, plug to
reduce risk of contamination.
• Lower implements attached to lift arms to relieve
hydraulic pressure from system before servicing.
• When servicing hydraulic pipe fittings, do not use
teflon tape. Use a liquid sealant that will dissolve
into system.
• Make sure all hydraulic connections are tight and
hydraulic hoses and lines are in good condition
before applying pressure to system.
WARNING
When checking for hydraulic leaks, do not use your
hands. Use cardboard or similar method to check for
leaks. Hydraulic fluid under pressure can get under skin
and will require immediate medical attention.

MAINTENANCE

Spark Plug
• Remove each plug and check condition.
• Good operating conditions are indicated if the plug
has a light coating of grey or tan deposit.
• A white blistered coating may indicate overheating,
while a black coating usually means an "over rich"
fuel mixture caused by a clogged air cleaner or
improper carburetor adjustment.
• Do not sandblast, wire brush or otherwise service a
plug in poor condition—best results are obtained
with a new plug.
• Set gap as indicated in engine manual.
Operator Presence System
Check operation daily. Repair if system does not shut
engine down when either blade control is engaged or
speed selector is not in neutral and operator present
levers are let go.
Decals and Labels
Replace any missing or illegible decals and labels. A
listing of decals and labels is provided at the front of
this book and the parts manual.
