MAINTENANCE
HYDRAULIC FLUID
Hydraulic fluid is used with the hydraulic pump to operate the hopper lift system and the side broom motor. The condition of the hydraulic fluid plays a large part in determining the life of the hydraulic system.
The hydraulic fluid used in the Tracer Gas/Diesel powered Floor Sweeper is Chevron 400 15W40. If a different hydraulic fluid is used, it must closely match the viscosity specification below.
SUS @ 100” (38º C)
SUS @ 210” (38º C)
This specification has a flat viscosity curve (high viscosity index). This means the thickness of the oil stays relatively constant over a wide temperature range. DO NOT use Automatic Transmission Fluid.
NOTE: The hydraulic components in the machine rely on system hydraulic fluid for lubrication. Dirty or contaminated fluid accelerates wear and malfunctions, and reduced component life.
HYDRAULIC FLUID RESERVOIR
The hydraulic fluid reservoir is located below the broom levers inside the machine. To check the fluid level remove the fill cap to read the dipstick attached to the cap.
NOTE: Do not overfill reservoir. Expansion of the hydraulic fluid when heated to the normal operating temperature can cause fluid to spill from the reservoir, or cause damage to the component.
The oil in the reservoir should be replaced every 500 hours of use. To drain hydraulic reservoir:
1.Turn off machine and set parking brake.
FOR SAFETY: Before leaving or servicing the machine, stop on level surface, apply parking brake, turn off machine and remove key.
2.Raise rear cover.
3.Disconnect batteries from machine.
4.Remove impeller.

5.Remove bolts (4) in feet of reservoir.
6.Shift reservoir forward so that short leg of reservoir drops down and rests on lower frame.
7.Remove upper hydraulic hose from reservoir.
8.Lift reservoir out of frame and rest on outer frame with open port above oil level.
9.Tilt reservoir back and remove last hose.
10.Reservoir may be emptied by pouring fluid out of ports.
11.The fluid strainer may be removed for inspection and to speed fluid drainage.
NOTE: Do not overfill the reservoir. Expansion of the hydraulic fluid when heated to the normal operating temperature can cause fluid to spill from the reservoir, or cause damage to the component.
If the reservoir is overfilled, use a suction type device to draw the excess hydraulic fluid from the reservoir.
HYDRAULIC FLUID LEAKS
Pressurized hydraulic fluid spraying from a very small hole can be very hard to see. Do not use hands to locate the leak. Use a piece of cardboard as shown below to find leaks.
When servicing machine, use a sheet of cardboard to locate leaking hydraulic fluid under pressure. Keep eyes and hands clear of leaks. Escaping hydraulic fluid under pressure can cause severe injury.

B – Cardboard
C – Pinhole Leak
