8 MAINTENANCE AND LUBRICATION
8.9 HYDRAULIC FILTER________________________________________________
The hydraulic system is protected by a 10 micron filter (A). Flow through the filter is monitored while you operate
the mower. When the difference in hydraulic pressure across the filter is greater than 16 to 20 psi (1.1 to 1.4
BAR), the hydraulic oil filter warning light on the combination gauge will illuminate. To make sure continued
protection of the hydraulic system, replace filter as soon as possible after light illuminates.
When you replace the filter, -
a Fill the new filter with hydraulic fluid and lubricate the filter O-ring with hydraulic fluid before you assemble
the new filter. Tighten the filter with your hand.
b Operate the engine at idle speed for five minutes to remove the air from the hydraulic system. The oil-level
light can illuminate and the horn can activate during the five minutes.
c Stop the engine and check the level of hydraulic fluid in the tank. Add the hydraulic fluid to the Full mark on
the gauge (Section 8.6).
NOTICE
During cold weather, the oil filter warning light can illuminate until the hydraulic fluid becomes warm. Wait until
the oil becomes warm and the warning light turn off before you operate the mower.
CAUTION
The Hydraulic Oil Can Damage Your Skin. Use Gloves When You Use Hydraulic Oil. If Hydraulic Oil Touches
Your Skin, Clean The Area Immediately.
CAUTION
Discard Used Hydraulic Oil As Shown In Local Safety Regulations.
