Still Wagner FM Type 447 Workshop Manual – FM12 FM14 FM17 FM20 Electric Forklift Repair PDF

Description

Still Wagner FM Type 447 Workshop Manual

This is the full workshop manual for the Still Wagner FM Type 447 series of electric industrial trucks. It is the reference document that the Still Wagner service organisation uses to specify, maintain and repair the FM-group vehicles, and it covers the FM12 (1.2 t), FM14 (1.4 t), FM17 (1.7 t) and FM20 (2.0 t) capacity trucks in a single volume. Every system on the truck is broken down into its assemblies with the technical data, adjustment values, removal and installation sequences, and testing routines needed to carry the work out correctly.

Because the manual is written for the FM group as a whole, the same procedures and specifications apply across all four capacity ratings unless a specific variant is called out. That makes this a practical single-source document whether you are working on one truck or a mixed fleet.

In total this is a complete service reference for the FM Type 447 truck. A technician gets the drive and steering systems documented down to potentiometer resistance values and error codes, the brake system with its three-part layout fully explained, the electrical architecture with the FPS and LAS modules described and their error codes itemised, and the hydraulic system with the valve blocks, pump unit and line break protection. The service software chapter means the same book also supports steering teaching-in, hydraulic commissioning and parameter changes through Servicemaster and WinPulsE.

What This Manual Enables You To Do

With the Still Wagner FM Type 447 workshop manual on hand, the jobs that would otherwise require guesswork become procedure-driven. You can remove and refit the drive motor using the correct rope and crowbar method, change the drive wheel to the specified 140 Nm tightening torque, adjust the electro-magnetic brake clearance to 0.2-0.35 mm, and set the braking moment against the factory dimension. The steering chapter takes you through setpoint and actual value potentiometer replacement, resistance checks around 1325 ohms at centre, and the full teaching-in routine, including the A/D converter calibration and flutter adjustment.

On the electrical side the manual is equally specific. The main current circuits for travel, generator braking and hydraulics are described at MOSFET level, the roll-away monitor is explained, and the FPS error codes FE01 through FE43 are listed with their causes. The hydraulic chapter gives the valve block variants, the diaphragm sizes that must not be altered, the pressure relief valve setting procedure based on measured operating pressure plus ten percent, and the maximum lowering speed check against the 60 cm/sec limit.

Getting the procedures and specifications right matters on equipment like this. A drive wheel nut torqued by feel, a brake clearance set too wide, a lowering speed left above the permissible value or a steering system not re-commissioned after a potentiometer change will all come back as faults, premature wear or, in the case of the brake system, a safety problem. The manual removes that risk by giving the actual values and the actual sequence.

The lubrication plan adds the routine side of ownership, covering the toothed gears, bolster bearings, chains, idling wheel bearings, mast profiles and sliding surfaces with their intervals and the correct lubricant types.
