Change Hydraulic System Filter
Service Interval: After the first 250 hours
Every 500 hours/Yearly (whichever comes first) thereafter
(Every 250 hours/Yearly if using Mobil 1 15W50)
Note: Use only Exmark Part No.
1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.
2.Carefully clean area around filter. It is important that no dirt or contamination enter hydraulic system.
3.Unscrew filter to remove and allow oil to drain from reservoir.
Important: Before reinstalling new filter, fill it with Exmark Premium Hydro oil and apply a thin coat of oil on the surface of the rubber seal.
Turn filter clockwise until rubber seal contacts the filter adapter, then tighten the filter an additional 2/3 to 3/4 turn.
4.Fill reservoir as stated in Check Hydraulic Oil
Level.
Exmark Premium Hydro Oil is recommended. Refer to the chart for an acceptable alternative:
Hydro Oil | Change Interval |
|
|
Exmark Premium Hydro | 500 Hours |
Oil (Preferred) |
|
Mobil 1 15W50 | 250 Hours |
|
|
5.Loosen filter 1/2 turn and allow a small amount of oil to leak from the oil filter (this allows air to be purged from the oil filter and supply hose from the hydraulic reservoir). Turn filter clockwise until rubber seal contacts the filter adapter. Then tighten the filter an additional 2/3 to 3/4 turn.
6.Raise the rear of machine up and support with jack stands (or equivalent support) just high enough to allow drive wheels to turn freely.
7.If either drive wheel does not rotate, one or both of the charge pumps (located on the top of the main pump as shown in Figure 12) may have lost their “prime”. Refer to Hydraulic System Air Purge section.
Note: Do Not change hydraulic system oil (except for what can be drained when changing filter), unless it is felt the oil has been contaminated or been extremely hot.
Changing oil unnecessarily could damage hydraulic system by introducing contaminates into the system.
Hydraulic System Air Purge
Service Interval: As required
Air must be purged from the hydraulic system when any hydraulic components, including oil filter, are removed or any of the hydraulic lines are disconnected.
The critical area for purging air from the hydraulic system is between the oil reservoir and each charge pump located on the top of each variable displacement pump (Figure 12). Air in other parts of the hydraulic system will be purged through normal operation once the charge pump is “primed”.
