SAFETY
The M Series stackers are very capable of causing seri-
ous injury or damage if adequate precautions are not
taken. By reading and following this manual, operator
injury may be prevented.
DO NOT INSTALL OR OPERATE THESE LIFTS
WITHOUT CAREFULLY READING THIS MANU-
AL. In order to provide for the safe operation of these
stackers, Presto Lifts Inc. has identied certain hazards
that may occur during the installation, maintenance and
use of these lifts.
WARNING!
• Do not perform any repair work on lifts if there is
a load on the platform or forks are in the raised or
lowered position.
• All personnel must stand clear of the lift when the
lift is in motion.
• Do not put hands or feet under forks or platform
while in motion.
• Do not put hands or feet on or near the mast
while the forks or platform is in motion.
• Do not stand, sit or climb on the lift.
• Do not exceed the load capacity.
• Place all loads centrally located on the lift forks
or platform.
• Do not place a load on a moving lift.
• Do not use the lift on soft, uneven or unstable
surfaces.
• Do not shock load the forks or platform. Materi-
als must be carefully placed rather than dropped.

occur in the use of the machine, and there are appropriate instructions or precautions which should be taken to
avoid these hazards. In some cases, there are consequences which may occur if instructions or precautions are
not followed. Below are the symbols and signal words along with their denitions referenced from ANSI Z535.4
- Product Safety Signs and Labels.

INSTALLATION
INSTALLATION
When the stacker arrives on a pallet the following steps
are to be followed:
1. Through the use of a forklift or overhead hoist, pick
the stacker unit up taking into consideration the center
of gravity. The center of gravity of the unit should be
adequately supported.
2. Once the unit is lifted from the pallet by a couple of
inches, remove the pallet from under the stacker.
3. Follow the next sections to ensure proper operation.
S E C T I O N 4
OPERATION
METHOD OF OPERATION:
In order to operate the lift follow these operating pro-
cedures.
1). To raise the platform or forks, pump foot pedal until
platform reaches desired height.
Table 1 – Hydraulic Oil Specications
If the lift will be used at normal ambient temperatures, Presto Lifts supplies the unit with Conoco Super Hydraulic
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 Conoco Super Hydraulic 32:
TYPE MANUFACTURER
AW32 .......................................... CITGO
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.
2). To lower lift, press release pedal down. Pressure on
release pedal controls speed of descent of load.
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.

OWNER’S MANUAL Page 10 M100, M200, M300 & M400 FOOT OPERATED LIFTS
S E C T I O N 7
TROUBLESHOOTING
If lift does not rise to full height:
It probably requires oil. (Check with lift in down
position.) To ll cylinder with oil, follow these
instructions.
There are two pipe plugs in the cylinder, Part No.
M427 (Vent Plug) and part No. M428 (Oil Level
Plug). Remove both plugs.
Put a good grade of hydraulic jack oil in the cylinder
through the top hole. When the oil reaches the level
of the bottom hole, replace both plugs. TOP PLUG
ISABREATHER PLUG, BE SURE TO REPLACE
PLUGS IN THEIR PROPER PLACES.
If lift does not hold load, or tends to drift down-
ward under a load:
Dirt particle may be obstructing seating of the
valve, allowing leakage.
If dirt particle is obstructing seating of the
valve:
Open release valve by pressing down on release
pedal. At the same time, pump foot lever three or
four strokes. Do this three or four times. Then place
some weight on the platform or forks and pump foot
lever until platform reaches its full height. Now,
lower lift six inches to a foot at a time. This should
dislodge dirt and lift should work properly.
S E C T I O N 6
SERVICE
To remove cylinder from lift:
1. Pump lift to above 12'' height and then prop plat-
form or forks up to keep it in raised position.
2. Step on release pedal and push ram down by
hand until it reaches its lowest point.
3. Slip chain off pulley and remove pulley as-
sembly.
4. Take off two bottom cap screws that hold cylin-
der in place and slide cylinder forward towards the
base legs of the lift. The cylinder can now easily
be removed.
To replace ram chevron set in hydraulic cylinder
assembly:
1. Remove hydraulic cylinder from lift and remove
Vent Plug (Part No. M427) and Oil Level Plug (Part
No. 428) and drain oil from cylinder.
2. Clamp pump body in vise, unscrew top hex nut
and remove outer cylinder.
3. Remove inner cylinder from pump making sure
not to distort or mar cylinder. Note: Do not use
pipe wrench.
4. Remove ram and replace chevron set.
5. Push ram into inner cylinder -- chevron end
last!
6. Reassemble and ll with clean hydraulic jack
oil.
