UnpackingOpen shipping container and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Pallet Truck is assembled and working properly.Individual trucks are assembled and ready to use. Pallet trucks purchased in crate quantities (6 units to a crate) require some assembly. Match the letter label on the handle assembly tothe letter label on the frame prior to assembly.AssemblyTools required for assembly: HammerFlat Head Screwdriver Pliers1.Insert the base of the handle into the pump bracket (Figure 1). Align the holes at the base of the handle with the holes in the pump bracket.2.Use a hammer to tap the handle pin into the holes of the pump bracket and handle (Figure 2). Use pliers to turn the handle pin until its holes align with the spring pin holes.3.Feed the screw head through the center hole in the handle pin (Figure 3). Using a screwdriver, pry up the cam and slip the screw head under the notch in the cam.4.Use a hammer to tap the spring pins (Figure2)into the holes on the pump bracket and handle pin.5.Tap out the pump retainer pin (Figure 1). NOTE: It is a good idea to remove any air bubbles that might have accumulated in the hydraulic system during shipping. Refer to Cleaning the Release Valve, on page 3.OperationFigure 1Figure 2Figure 3Smart Lifting
This pallet truck is designed for use with open style pallets or skids only. Closed style pallets must be placed on top of fork prior to use.1. Insert the forks into the pallet.Owner’s Manual // M25 Series Pallet TruckOriginal Version // English // v1.0 // January 2021 // Page 3

2.To raise the fork, push control lever all the way down, and pump the handle until the desired fork height is reached.3.To move the handle without a󾪡ecting the fork setting, set the control lever in the center neutral position. The load can now be pushed or pulled using the handle.4.To lower the fork, pull lever all the way up. Allow the load to descend slowly in a controlled manner. The lever is spring loaded and will return to the neutral position when released.When not in use, do not allow heavy loads to remain on the fork for an extended period of time. Always lower fork completely when not in use.Up-Down Cam AdjustmentWhen pumping the handle with the lever in neutral position, there should be no movement of the fork. If there is fork movement, the cam must be adjusted:1.Place lever in neutral position.2.Loosen the hex nut .3.Adjust the socket head cap screw while pumping the handle, until there is no longer any movement of the ram.4.Tighten the hex nut .Cleaning the Release Valve (Bleeding the Pump)Over time, the hydraulic pump may become clogged with debris or air bubbles causing improper function.Clean the release valve as follows:1.Pump handle quickly, raising pallet truck to full extent. Pull lever all the way up in order to lower the fork, while continuing to pump the handle.2.When fork has lowered completely, the valve has been 󾪣ushed. Repeat if necessary.MaintenanceCheck the oil level annually by removing the oil plug on top of the pump housing. When changing or adding oil, 󾪢ll the tank through the oil plug hole to 80% capacity with hydraulic jack oil, about 2-1/2 deep in pump housing. See Figure 4. Do not use any other type of oil. When 󾪢nished, replace oil plug .Figure 4Wheel bearings are sealed and require no lubrication. The crank shaft features oil lite bushings that also require no lubrication.Lightly oil all other moving parts.Seal and O-Ring Replacement for Ramand Plunger Piston1.Raise the pallet truck by pumping handle.2.Remove spring pin . This will free the pump and handle assembly from the pallet truck.3.Remove the oil plug , turn pump over andempty the oil into a suitable container. Pump handle until all oil has drained. Dispose of used hydraulic oil according to local disposal regulations.4.Pull out plunger piston and/or ram piston .5.Remove all o-rings and seals. See Figure 5.6.Insert new o-ring or seal one at a time makingsure to replace with the same size that was removed.Reassemble and 󾪢ll the oil tank through the oil plug hole to 80% capacity with new hydraulic jackoil, about 2-1/2 deep in pump housing. See Figure 4.Figure 53635 34l
