Combi-Lift Service Manual – OEM Factory Specs for Your Forklift

If you’re turning wrenches on a Combi-Lift forklift, you need factory specs. Not some reprint from a third-party that guesses on the coolant type. This is the real thing: the original Combi-Lift Service Manual, 31 pages of procedures that match what the factory techs used. I’ve seen too many guys snap bolts because they used aftermarket torque values. This manual gives you the numbers from the factory — rear wheel nuts at 568 ft-lbs, front at 340 ft-lbs. Page 2 lays out the initial 100-hour service checklist. Page 3 has the engine oil viscosity table by ambient temperature. You get the fuel filter replacement, the cooling fan circuit update, the whole electrical circuit diagrams.

Initial 100-Hour Service Checklist

Every Combi-Lift comes with a mandatory service at 100 hours. The manual lists it in order: change engine oil and filter, replace the suction filter, check the fuel filter, adjust the fan belt tension. Torque those wheel nuts to spec. The grease point chart tells you exactly where to hit it. If you skip this service, you’ll get hydraulic contamination or a thrown belt. I’ve seen it.

What Does the Manual Cover for the Fuel System?

Section 3.3 is the fuel filter. It’s a simple replacement, but the manual tells you the correct filter part number and the sequence to bleed air. No guesswork. The fuel system on these machines can be sensitive to water. The initial service at 100 hours includes checking for leaks. If you ignore it, you’ll be replacing injectors. The manual also covers coolant level checks and radiator cleaning. Engine cooling is covered in Section 1.3 and Section 3.4.

4-Way Options and Modes Explained

From Section 7 to 10, the manual covers the four-direction capability: Frontal Mode, Sideward Mode, Carousel Mode, and the 4-Way Options. Each mode has its own electrical circuit diagram. The four direction electrical circuit is broken into six diagrams (Sections 11.1 to 11.5). If your Combi-Lift won’t switch modes, you trace the wiring using these diagrams. Don’t rely on a generic schematic — the factory wire colors and pinouts are only in this manual.

Check the Cooling Fan Circuit Before You Assume a Thermostat

Section 6.2 is the cooling fan circuit. If the engine overheats, most guys replace the thermostat first. The manual shows you the fan circuit, including an update (Section 6.3). Check the fan relay and wiring before you tear into the cooling system. The hydraulic oil cooler also ties into this. The manual’s electrical circuit (Section 6) is split into two parts — make sure you have both.

Hydrostatic Transmission: Bypass Condition and Brake Release

Section 13 covers the hydrostatic transmission bypass condition. If the machine won’t move, you need to know how to release the brakes mechanically (Section 14). Section 15 is checking rear motor charge pressure. The manual gives the pressure spec and the test point. Do NOT guess on charge pressure — low pressure ruins the hydrostatic motor. The Manual Transmission on a car is different; this is a hydrostatic drive, not a gearbox.

For additional training material, the Combi-Lift Service Training Pack Index gives you a structured approach to these repairs. If you work on other equipment, the White Outdoor LT-5 700 Series 2005 Service Manual – OEM Factory Specs follows the same standard. And the Maruti MB308 Service Manual – OEM Factory Specs for Proper Repairs is another example of factory documentation done right.

Section 16 covers dash components, Section 17 the fuse box. Section 18 explains hydrostatic motor operation. The synchronized hydraulic steering (Section 12) is critical for the four-direction steering system. Without the diagrams, you’ll waste hours tracing lines. The manual is 31 pages, but every page has a purpose. No filler.

Source Authenticity: OEM vs Aftermarket

I don’t trust aftermarket documentation. I’ve seen manuals that list 500 ft-lbs for a bolt that should be 340. That costs you a wheel. This Combi-Lift Service Manual is scanned from the original factory binder. The page numbers match, the diagrams are readable. You get the exact same data the dealer techs get. No edits, no omissions. That’s why I tell my guys: if it’s not OEM, don’t torque to it.

Audience Fit: Who Needs This Manual?

If you own a Combi-Lift forklift, you need this. Whether you’re a fleet manager doing PMs or a home garage guy with a used forklift, you can’t afford to guess. The manual walks you through the 100-hour service, the hydraulic circuit, the electrical system. Beginners should read the initial service section first. Experienced guys will go straight to the torque specs and circuit diagrams. It covers engine, fuel, electrical, and cooling — the four systems that fail most often.

Does this manual cover the diesel engine specific to my Combi-Lift?

Yes, it covers the engine oil grades and viscosity based on ambient temperature. The manual references a specific engine but does not specify the make. However, the oil and filter change procedures are generic to the engine installed. If you need exact engine specs, contact Combi-Lift directly. The manual also includes the initial service checklist that includes engine oil change, filter replacement, and checking the fan belt. For the fuel system, it tells you to replace the fuel filter and check for leaks. So yes, it covers the engine system.

How many pages is the manual?

31 pages.

Does it include torque specs for the entire forklift?

It includes wheel nut torque specs on page 2 (rear 568 ft-lbs, front 340 ft-lbs). For other bolts, the manual references checking tightness but does not list individual torque values for every fastener. You’ll need a general fastener torque chart for those. The hydraulic circuit pressures are not given in the excerpt; you may need to check the system diagrams.

Can I use this manual for a different forklift model?

No. This is specific to the Combi-Lift brand. If you have a different brand, look for its own OEM manual. The Manual Transmission section here is not applicable to a standard forklift; it’s the hydrostatic drive. Don’t apply Combi-Lift specs to other machines.

Bottom line: if you’re serious about keeping your Combi-Lift running without breakdowns, get the factory data. Aftermarket manuals will cost you time and parts. This OEM service manual is the one I keep on my bench. Access the Factory Manual and put it on your tablet or print it out. You’ll thank me when you’re torquing those rear wheels to 568 ft-lbs instead of guessing.
