S E C T I O N 5
MAINTENANCE
ROUTINE MAINTENANCE:
1). Grease wheels and casters at least once a month to maintain easy roll of lift.
2). Do not overload the lift. All foot operated Presto Manual Stackers have a maximum rated capacity
of 1000 lbs.
3). Use only hydraulic oil in the hydraulic system. NEVER USE HYDRAULIC BRAKE FLUID.
Table 1 – Hydraulic Oil Specifications
If the lift will be used at normal ambient temperatures, Presto Lifts supplies the unit with
Citgo AW 32 oil. This may be replaced by any other good quality oil with 150 SSU at 100°
F and rust and oxidation inhibitors and anti-wear properties.
If the lift will be used at ambient temperatures below 0°F, use aircraft hydraulic oil. Use
Type 15 aircraft hydraulic oil.
The following are equivalent to CITGO AW32:
TYPE MANUFACTURER
DTE 24 ............................. EXXON/MOBIL
NUTO H32 ........................ EXXON/MOBIL
AMOCO AW32.................. CHEVRON (AMOCO CO.)
CAUTION!
It is very important to keep the hydraulic oil free of dirt, dust, metal chips,
water, and other contamination. Most of the problems with hydraulic systems
are caused by contamination in the oil.
