Regular Maintenance
WARNING
Replacement parts must be the same and
installed in the same position as the original
parts or fire could result.
Inspect Muffler and Spark Arrester
Inspect the muffler for cracks, corrosion, or other
damage. Remove the spark arrester, if equipped,
and inspect for damage or carbon blockage. If
replacement parts required, make sure to use only
original equipment replacement parts.
Change Oil & Filter
1. Warm engine by running for a few minutes.
(Refer to the engine operator’s manual for oil &
filter replacement instructions.)
2. Remove the oil drain hose (A, Figure 12) from
the cable clamp (B) on the right-hand side of the
frame and route the hose through hole in the
engine deck as shown in Figure 12.
3. Place a small pan under the oil drain hose to
catch the oil. Using the appropriate tools, remove
the cap from the oil drain hose (A) and drain the
engine oil.
4. After draining, replace the cap and wipe up any
spilled oil. Reinstall the oil drain hose into the
cable clamp to retain the hose during normal
operation.
5. Place an absorbent shop cloth under the engine
oil filter. Remove the engine oil filter and replace
with a new one.
6. Remove the shop cloth and wipe up any spilled
oil.

Check Hydraulic Oil Level
1. Before removing the reservoir cap, make sure the
area around the reservoir cap and fill neck of the
reservoir is free of dust, dirt, or other debris.
2. Unscrew the reservoir cap (B, Figure 13).
3. Look down the filler neck of the hydraulic oil
reservoir (A, Figure 16) and observe the oil level.
When cold, the oil level should be approximately
4” (10 cm) below top of the filler neck.
4. If necessary, add either Mobil 1™, 15W-50
synthetic oil or Castrol Syntec™ 5W-50 oil. DO
NOT use conventional oils.
5. Reinstall the reservoir cap.

Change Hydraulic Oil Filter
Change Interval:
Every 250 Hours
Filter Part Number:
1719168
NOTE: Removing the oil filter from the filter base
will drain the oil reservoir. Have a suitable container
ready to catch any spilled oil. Ferris recommends this
be a dealer-only service item.
1. Locate the transmission oil filter (A, Figure 14).
2. Lubricate the new filter base with a few drops of
transmission oil. Fill the filter half full of oil.
3. Clean the area around the filter base and remove
the filter. Do NOT drain the hydraulic system oil.
4. Thread the new filter onto the filter base until the
gasket makes contact, then tighten 3/4 of a turn
more.
5. Run the unit for several minutes and check the
transmission oil level.
IMPORTANT NOTE: Use caution after changing
the filter; air in the hydraulic system may affect the
responsiveness of the control levers. Repeat step 5
until the air is out of the system.
