Servicing the Hydraulic
System
Checking the Hydraulic Fluid
Check the hydraulic fluid level before engine is first
started.
Check the hydraulic fluid level after first 8 operating
hours.
Check the hydraulic fluid level after every 25 operating
hours.
Fluid Type: Mobil 1 15W-50 synthetic motor oil or
equivalent synthetic oil.
Important
Use oil specified or equivalent. Other
fluids could cause system damage.
Hydraulic System Oil Capacity: 67 oz. (2.0 l)
Note: There are two ways of checking the hydraulic oil.
One is when the oil is warm and one is when the oil is
cold. The baffle inside the tank has two levels depending
if the oil is warm or cold.
1. Position machine on a level surface and set the parking
brake.
2. Clean area around filler neck of hydraulic tank
(Fig. 49).
3. Remove cap from filler neck. Look inside to check if
there is fluid in the reservoir. (Fig. 49).
4. If there is no fluid, add fluid to the reservoir until it
reaches the cold level of the baffle.
