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) 404-445
SUS @ 210” (38º C) 78-84
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.
