PAGE 48 — MAYCO LS450 CONCRETE PUMP • OPERATION MANUAL — REV. #2 (02/23/21)
The hydraulic system is factory-filled with Shell Tellus 46
hydraulic oil, typically used in ambient temperature ranges
of 39–90°F (4–32°C). The machine reservoir temperature
range is 100–170°F (38–77°C).
If the machine is used in areas with ambient temperatures
constantly above 90°F (32°C), the use of hydraulic fluid
designated with an ISO rating of 68 is recommended. In
areas with ambient temperatures constantly below 32°F
(0°C), use oil with an ISO rating of 32.
PUMP LUBRICATION
The following components should be greased daily (or
hourly if necessary). See Figure 54.
Main hydraulic cylinders (2 grease fittings)
Swing axle bushing (1 grease fitting)
Shuttle cylinder (2 grease fittings top and bottom)
