Oil & Filter Change; Engine Maintenance; Inspect Muffler / Spark Arrester; Check Hydraulic Oil Level - Ferris IS1500Z Series Operator's Manual

Regular Maintenance
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 15) from
the cable clamp (C) on the right-hand side of the
frame and route the hose towards the rear of the
machine as shown in Figure 15.
3. Place a small pan under the oil drain hose to
catch the oil. Using the appropriate tools, remove
the cap (B, Figure 15) 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.

Engine Maintenance

Refer to engine owner's manual for all engine
maintenance procedures and recommendations.

Inspect Muffler / 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 are required, make sure to use
only original equipment replacement parts.

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 16).
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.
