OWNER’S MANUAL Page 4 M100, M200, M300 & M400 FOOT OPERATED LIFTS 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. OWNER’S MANUAL Page 5 M100, M200, M300 & M400 FOOT OPERATED LIFTS S E C T I O N 6 SERVICE To remove cylinder from lift: 1. Pump lift to above 12'' height and then prop platform 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 assembly. 4. Take off two bottom cap screws that hold cylinder 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 fill with clean hydraulic jack oil. 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 fill 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 IS A BREATHER PLUG, BE SURE TO REPLACE PLUGS IN THEIR PROPER PLACES. If lift does not hold load, or tends to drift downward 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.
