Husqvarna 917.27909 - Manual (Page 18)

MAINTENANCE
BATTERY
Your tractor has a battery charging system which is sufficient
for normal use. However, periodic charging of fhe battery
with an automotive charger will extend its life.
• Keep battery and terminals clean.
• Keep battery bolts tight.
• Keep small vent holes open.
• Recharge at 6-10 amperes for 1 hour.
NOTE: The original equipment battery on your tractor is
maintenance free. Do not attempt to open or remove caps
or covers. Adding or checking level of electrolyte is not
necessary.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause
the battery to “leak” power.
Remove terminal guard.
Disconnect BLACK battery cable first then RED bat­
tery cable and remove battery from fracfor.
Rinse the battery with plain water and dry.
Clean terminals and battery cable ends with wire brush
until bright.
Coat terminals with grease or petroleum jelly.
Reinstall battery (See “REPLACING BATTERY” in
the SERVICE AND ADJUSTMENTS section of this
manual).
V-BELTS
Check V-belts for deterioration and wear after 100 hours
of operation and replace if necessary. The belts are not
adjustable. Replace belts if they begin to slip from wear,
TRANSAXLE COOLING
Keep transaxle free from build-up of dirt and chaff which
can restrict cooling.
CHECK TRANSAXLE OIL LEVEL
(See Fig. 14)
• Block up rear axle securely.
• Remove left rear wheel by removing hub bolts.
• Remove filler plug from transaxle. Cil level must be
even with plug threads. If necessary, fill with SAE 30
motor oil, API SG-SL. Replace filler plug.
• Reassemble wheel to hub.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service
classification SG-SL. Select the oil’s SAE viscosity grade
according to your expected operating temperature.
SAE VISCOSITY GRADES

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

FIG. 15
NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32°F. Check your engine oil level more frequently to avoid
possible engine damage from running low on oil.
Change the oil after every 50 hours of operation or at least
once a year if the tractor is not used for 50 hours in one
year.
Check fhe crankcase oil level before starfing the engine
and after each eight (8) hours of operation. Tighten oil fill
cap/dipstick securely each fime you check the oil level.
TC CHANGE ENGINE GIL (See Figs. 15-16)
Determine temperature range expected before oil change.
All oil must meet API service classification SG-SL.
• Be sure tractor is on level surface.
• Cil will drain more freely when warm,
• Catch oil in a suitable container.
• Remove oil fill cap/dipstick. Be careful not to allow dirt
to enter the engine when changing oil.
• Install the drain tube onto the valve.
• Gpen drain valve by using a 7/16" (11mm) wrench
turning counterclockwise.
