Exmark VH15KA362, VH15KA483 manual

4.1.8Check hydraulic oil level: Service Interval: 40 hr.

a)Stop engine and wait for all moving parts to stop.

b)Clean area around hydraulic reservoir cap and remove cap. Oil level should be to the top of the baffle inside the tank. If not, add oil. Use only Mobil 1 15W-50 synthetic motor oil. Replace hydraulic reservoir cap and tighten until snug. Do not overtighten.

NOTE: The baffle is labeled “HOT” and “COLD”. The oil level varies with the temperature of the oil. The “HOT” level shows the level of oil when it is at 225° F. (107°C). The “COLD” level shows the level of the oil when it is a 75°F (24°C). Fill to the appropriate level depending upon the temperature of the oil. For example: If the oil is about 150°F (65°), fill to halfway between the “HOT” and “COLD” levels. If the oil is at room temperature (about 75°F (24°C)), fill only to the “COLD” level.

4.1.9Change hydraulic system filter:

Service Interval: After First 250 hrs, then yearly thereafter.

Note: Use Exmark Part No. 109-4180 for Summer use above 32° F (0° C)and use Part No. 1-523541 for Winter use below 32° F (0° C). (Refer to 2.6.2 for Filter Specifications.)

a)Place unit on a level surface. stop. Engage parking brake.

Stop engine and wait for all moving parts to Remove key or spark plug wire(s).

b)Carefully clean area around filter. It is important that no dirt or contamination enters the hydraulic system.

c)Unscrew filter to remove and allow oil to drain from reservoir.

IMPORTANT: Before re-installing new filter, fill it completely with Mobil 1 15W- 50 and apply a thin coat of oil on the surface of the rubber seal. Turn filter clockwise until rubber seal contacts the filter adapter. Do not tighten yet.

d)Fill reservoir as stated in Section 4.1.8.

e)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.

f)Raise the rear of the machine up onto jack stands high enough to raise the drive wheels off of the ground. Run machine to allow any other air to be purged from the hydraulic system and recheck the oil level.

g)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 4) may have lost their “prime”. Refer to Section 4.1.10.

h)DO NOT change hydraulic system oil (except what can be drained when changing filter) unless it is felt that oil has been contaminated. Changing oil unnecessarily could damage the hydraulic system by introducing contaminates into the system.

4.1.10Hydraulic system air purge procedure:

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. (See Figure 4).

Air in other parts of the hydraulic system will be purged through normal operation once the charge pump is “primed”.
