MAINTENANCE & ADJUSTMENTS

Safe servicing practices

This product is capable of amputating hands and feet and 

throwing objects. Always follow all safety instructions to avoid 
serious injury or death.

Service precautions

Unless specifically required, 

DO NOT

 have engine run-

ning when servicing or making adjustments to mower. 
Park the machine on level ground. Place steering control 
levers in the park brake position, disengage deck clutch, 
lower deck, remove ignition switch key and disconnect 
negative battery cable before doing any maintenance. 
Wait for all movement to stop before adjusting, cleaning 
or repairing. Repairs or maintenance requiring engine 
power should be performed by trained maintenance per-
sonnel only. To prevent carbon monoxide poisoning, be 
sure proper ventilation is available when engine must be 
operated in an enclosed area. Read and observe safety 
warnings in front of manual.

Before working on or under the deck, make certain 
engine cannot be accidentally started. Shut engine off, 
remove ignition switch key and disconnect negative bat-
tery cable for maximum safety. Repairs or maintenance 
requiring engine power should be performed by trained 
maintenance personnel only.

Except when changing or checking belt, 

always

 keep belt 

covers on mower deck for safety as well as cleanliness.

Use a stick or similar instrument to clean under the 
mower making sure that no part of the body, especially 
arms and hands are under mower.

Keep your machine clean and remove any deposits of 
trash and clippings, which can cause engine fires and 
hydraulic overheating as well as excessive belt wear. 
Clean up oil or fuel spillage. Allow machine to cool 
before storing. 

Clean flammable material from machine. Prevent 
fires by keeping engine compartment, top of deck, 
exhaust area, battery, fuel line, fuel tank and opera-
tor’s station clean of accumulated trash, grass clip-
pings, and other debris. Always clean up spilled fuel 
and oil.

Always wear adequate eye protection when servicing the 
hydraulic system and battery, or when grinding mower 
blades and removing accumulated debris. 

Use extra caution when handling gasoline and other 
fuels. They are flammable and vapors are explosive.

Never attempt to start engine when there is a strong odor 
of gasoline fumes present. Locate and correct cause.

Never remove the fuel cap or refuel mower while engine 
is running; never refuel near an open flame or near 
devices which can create a spark. Refuel outdoors. Never 
refuel or drain the fuel from the machine indoors.

Never run the engine in an enclosed area unless exhaust 
is vented to the outside. Exhaust gases contain carbon 
monoxide which is odorless and deadly poison.

Never attempt to make any adjustments or repairs to the 
mower drive system, mower deck or any attachment 
while the mower engine is running or deck clutch is 
engaged. Repairs or maintenance requiring engine power 
should be performed by trained maintenance personnel 
only.

Never work under the machine or attachment unless it is 
safely supported with jack stands. Make certain machine 
is secure when it is raised and placed on the jack stands. 
The jack stands should not allow the machine to move 
when the engine is running and the drive wheels are 
rotating. 

Use only certified jack stands.

 Use only appro-

priate jack stands, with a minimum weight rating of 2000 
pounds (907 kg) to block the unit up. Use in pairs only. 
Follow the instructions supplied with the vehicle stands.

Do not touch hot parts of machine.

Keep nuts and bolts tight, especially the blade attachment 
bolts. Keep equipment in good working condition.

Never tamper with safety devices. Check their proper 
operation regularly.

Stop the engine before removing the grass catcher or 
unclogging the discharge chute. Never clear the discharge 
chute with the engine running. Turn off the engine and be 
sure the blades have stopped before cleaning. Use a stick 
to clear a plugged discharge area. 

Never use your hand!

Grass collection system components are subject to wear, 
damage and deterioration, which could expose moving 
parts or allow objects to be thrown. Frequently check 
components and replace with manufacturer’s recom-
mended parts, when necessary.

Exercise caution when working under the deck as the 
mower blades are extremely sharp. Wrap the blade(s) or 
wear gloves and use extra caution when servicing them.

Use only genuine BigDog

®

 Mowers replacement parts to 

ensure that original standards are maintained.

Service introduction

Regular maintenance is the best prevention for costly 

downtime or expensive, premature repair. The following pages 
contain suggested maintenance information and schedules 
which the operator should follow on a routine basis. For more 
detailed information order the correct Parts Manual and General 
Service Manual for your unit. Refer to the 

Product Literature

section of this manual.

Remain alert for unusual noises, they could be signaling a 

problem. Visually inspect the machine for any abnormal wear or 
damage. A good time to detect potential problems is while 
performing scheduled maintenance service. Correcting the 
problem as quickly as possible is the best insurance.

Clear away heavy build-up of grease, oil and dirt, especially 

in the engine and under the seat platform areas; minute dust 
particle are abrasive to close-tolerance engine and hydraulic 
assemblies.

Inspect mower daily

 for grass clippings and wire and string 

tangles. The underside of the mower deck will collect a build-up 
of grass clippings and dirt, especially when grass is wet or has
