MAINTENANCE
To adjust anti-scalp rollers
Deck has anti-scalp rollers.
Anti-scalp rollers are properly adjusted when 
they are just slightly off of the ground when 
the deck is at the desired cutting height in the 
operating position. Anti-scalp rollers then 
keep the deck in the proper position to help 
prevent scalping in most terrain conditions.
1. Adjust the deck to the desired cutting 
height (see “TO ADJUST DECK 
CUTTING HEIGHT” in the operation 
section of this manual).
2. Using a 3/4 wrench and a 9/16 wrench, 
remove the nut and shoulder bolt from 
the anti-scalp roller.
3. Lower the anti-scalp roller to the ground, 
and raise it up to the next highest hole.
4. Replace and tighten the nut and shoulder 
bolt.
5. Be sure to adjust all of the anti-scalp 
rollers to the same position.
6. Be sure to readjust the anti-scalp rollers 
if the cutting height is changed.

MAINTENANCE
Cleaning and Washing
Regular cleaning and washing, especially 
under the mower deck, will increase the 
machine’s lifespan. Make it a habit to clean 
the machine directly after use (after it is 
cooled), before the dirt sticks.
Do not spray water on the top of the mower 
deck. Use compressed air to clean the top 
side of mower deck. Regulary clean deck and 
underside of deck, avoid spraying engine and 
electrical components with water.
Caster Wheels
Check every 200 hours. Lift front of unit off of 
ground so caster wheels can rotate freely. 
Tighten caster bolt then back off 1/2 turn. 
Check that wheel rotates freely. If wheel does 
not rotate freely back the caster bolt off in 1/4 
turn increments until wheel rotates freely.
Foam filled tires or solid tires will void the 
warranty.
Hardware
Check daily. Inspect the entire machine for 
loose or missing hardware.

Cleaning
Use protective glasses when 
cleaning and washing.

IMPORTANT INFORMATION
DO NOT add any type of tire liner or foam 
fill material to the tires. Excessive loads 
created by foam filled tires will cause 
premature failures.
Only use O.E.M. specified tires.

LUBRICATION
Lubrication
Lubrication Schedule 
General
Remove the ignition key to prevent unintentional movements during lubrication.
When lubricating with an oil can, it must be filled with engine oil.
When lubricating with grease, unless otherwise stated, use a high grade molybdenum disulfide grease.
For daily use, the machine shall be lubricated twice weekly.
Wipe away excess grease after lubrication.
It is important to avoid getting lubricant on the belts or the drive surfaces on the belt pulleys. Should this 
happen, attempt to clean them with spirits. If the belt continues to slip after cleaning, it must be replaced. 
Gasoline or other petroleum products must not be used to clean belts.

LUBRICATION
Lubricating the Cables
If possible, grease both ends of the cables and move the controls to end stop positions when lubricating. 
Refit the rubber covers on the cables after lubrication. Cables with sheaths will bind if they are not 
lubricated regularly. If a cable binds, it can disrupt operation.
If a cable binds, remove the cable and hang it vertically. Lubricate it with light engine oil until the oil begins 
to escape from the bottom. 
Tip: Fill a small plastic bag with oil and tape it so that it seals against the sheath and allow the cable to hang 
vertically from the bag overnight. If you do not succeed in lubricating the cable, it must be replaced.
Lubricating in Accordance with the 
Lubrication Schedule
1. Caster wheels
Lubricate with a grease gun. One zerk for 
each bearing, two strokes. Use only good 
quality grease. See General in Lubrication.
2. Engine Oil (Briggs & Stratton)
Changing the Engine Oil
The engine oil should be changed for the first 
time after 5-8 hours of operation. Thereafter, 
it shall be changed every 50 hours.

valve by turning and pulling out the black 
sleeve.
5. Allow the oil to run out into the container.
6. Then close the oil drain valve.
7. Remove hose and install the yellow cap. 
The cap must be installed to stop flow if 
the valve is opened by mistake.
8. Replace the oil filter if necessary.
9. Fill with new engine oil in accordance 
with Checking the Oil Level. 
10. Start the engine. Run it for a few 
seconds. Stop and re-check the oil level.IMPORTANT INFORMATION

Checking the oil level
Check the oil level in the engine when the 
machine is standing level and the engine is 
stopped. 
Remove the dipstick, wipe it clean, and then 
replace it. 
The dipstick should be screwed into place.
Take the dipstick out again and read the oil 
level.
The oil level shall lie between the markings 
on the dipstick. If the level is approaching the 
”ADD” mark, fill the oil to the ”FULL” mark on 
the dipstick. 
Never fill above the ”FULL” mark.
The oil is filled through the hole for the 
dipstick.
API class SF, SG, SH, SJ or higher must be 
used
Synthetic oil SAE 5W-30 or 10W30 is 
recommended at all temperatures.
Mineral oil SAE 5W-30, 10W30 can be used 
between 0 °F/-18 °C and 40 °F/+5 °C. At 
temperature above 40 °F/+5 °C single grade 
SAE 30 must be used.
The engine holds 1.5 quarts (1.4 liters) of oil 
excluding the filter; including the filter 1.6 
quarts (1.5 liters).
2. Changing the Oil Filter
1. Drain the engine oil following the 
procedure described in Engine Oil/
Change Engine Oil section. 
2. Remove the oil filter. If necessary, use a 
filter remover.
3. Wipe new, clean engine oil on the seal of 
the new filter.
4. Mount the filter by hand with + 3/4 turn.
5. Run the engine warm, then check that 
there are no leaks around the oil filter
