Engine Manufacturer And Type:
Varied, likely internal Komatsu or licensed industrial engines (e.g., based on LP gas, diesel, or gasoline models as indicated by H/J variants)
Lift Capacity:
Ranges typically from 2000 kg to 3000 kg (4,500 lbs to 6,500 lbs) depending on the specific model (FG20/25/30, FD20/25/30)
Fuel Types:
Propane (LP Gas - indicated by 'H'), Diesel ('D'), Gasoline (implied for non-'H'/'J' variants, or potentially 'J' indicates a specific engine family)
Oil Type:
Specific SAE viscosity grade and API service classification required (detailed in manual)
Type:
Likely hydrostatic transmission (HST) or torque converter automatic transmission, common for industrial forklifts of this era.
N/A:
Not specified, typically one primary transmission type per series.
Transmission Fluid:
Specific ATF or hydraulic fluid type and specification required (detailed in manual)
N/A:
No specific safety ratings (like NHTSA or Euro NCAP) are applicable to industrial forklifts in the same way as passenger vehicles.
Operator Safety Systems:
Operator presence system (operator seat switch), parking brake, safety interlocks.
Operator Protection:
Overhead guard (Forks Protection Device - FPD), operator restraints (seat belt), secure operator station.
Engine Oil Change:
Typically every 250-500 operating hours, depending on operating conditions and specific engine model.
Hydraulic Fluid Change:
Usually every 1000-2000 operating hours or as per manual recommendation.
Filter Replacements:
Fuel filters, oil filters, hydraulic filters, and air filters typically replaced at scheduled maintenance intervals coinciding with fluid changes.
Engine Oil Grade:
Specific SAE viscosity (e.g., SAE 30, 10W-30, 15W-40) and API classification (e.g., CD, CE, CF) detailed in manual.
Transmission Fluid Type:
May require specific ATF fluid or a dedicated hydraulic transmission fluid, specified in manual.
Hydraulic Fluid Type:
Typically ISO VG 32, 46, or 68 hydraulic oil, depending on operating temperature and pump requirements, as specified in manual.
Coolant Type:
Ethylene glycol based coolant with appropriate corrosion inhibitors, usually a 50/50 mix with distilled water.
Common Wear Items:
Mast rollers, forks, hydraulic hoses, seals, brake components, tires, engine mounts.
Electrical Component Wear:
Contactors, limit switches, wiring harness integrity can degrade over time, especially in dusty or wet environments.
Hydraulic System Performance:
Slow lift or tilt functions can indicate pump wear, internal leaks, or blockages in the hydraulic circuit.
Cleanliness:
Maintaining overall cleanliness of the forklift, especially engine bays and hydraulic components, is crucial for longevity.
Komatsu Forklift Division:
Komatsu Ltd. is a renowned manufacturer of construction machinery, with a significant division dedicated to industrial vehicles like forklifts.
Fg Fd Series:
The FG/FD series represents Komatsu's established line of internal combustion engine forklifts, evolving through various generations (indicated by series numbers like -14).
Series Production Period:
The '-14' designation typically refers to models produced in the late 1990s to early 2000s, but precise years would require cross-referencing Komatsu's production data.
