TECHNICAL DATA
ENGINE
• All engines utilize an ECCS that continu-
ously monitors data from the fuel pressure,
accelerator throttle position, mass air-flow
sensor, and heated oxygen sensor – for
improved fuel economy, smooth operation,
reliable starting in cold weather, and high
performance throughout the operating
range. An electronic throttle governor pro-
tects the engine against over-rev damage.
• Crankshaft and camshaft position sensors
provide information to the ECCS for optimum
ignition and fuel injection timing. Each cylinder
has an individual ignition coil for precise
control and reliability.
by automatically limiting engine speed
during high-temperature operation. If the
engine coolant temperature exceeds safe
operation temperature, the engine will be
shut down. An illuminated indicator on the
instrument console indicates high-temper-
ature operation, and gives the operator
warning of engine shutdown.
• The aluminum alloy cylinder head has large
intake and exhaust valves and a semi-hemi-
spherical combustion chamber for efficient
fuel consumption.
K21 (2.1 liter) gasoline/LPG, 4-cylinder,
in-line engines with Engine Concentrated
Control Systems (ECCS) exceed EPA emissions
standards. These low-RPM, high-torque in-
dustrial engines offer reduced maintenance
requirements, exceptional emissions controls,
fast acceleration, high performance, reliable
durability and enhanced serviceability.
• There are three engine fuel choices:
gasoline multi-port fuel injection, LPG
single-port (throttle body) fuel injection,
or a dual-fuel system with easy switching
at the flip of a switch. All engines are
equipped with 3-way catalytic converters
and closed-loop exhaust systems.
• The engine block is designed with five main
bearings. All main and rod bearings are
micro-grooved to improve lubrication and
reduce wear.
• An engine coolant temperature sensor
and controller protects the engine against
damage due to high engine temperature
TECHNICAL DATA
TRANSMISSION
• Comfort seat has built-in lumbar support,
retractable seat belt, lateral restraint sys-
tem, and fore and aft adjustment.
• Hydraulic control levers are positioned for
optimum access and ease of use. Inter-
national symbols on the contoured grips
indicate the function.
• Tilting steering console has small-diameter
steering wheel and electronic instrumen-
tation. Tilt is infinitely adjustable, with
extended room between the engine cover
and console.
• Wide-open floorboard has suspended
brake and inching pedals with ribbed rub-
ber pads for comfort and safety. Integral
accelerator mechanism has a transfer roller
for smooth operation.
• Full-width rubber floor mat provides a
large, non-slip surface and reduces noise,
vibration and heat.
FUEL SYSTEM
Hamech single-speed, powershift transmis-
sion is specifically designed for industrial
applications.
• Column-mounted electrical shift lever gives
the operator easy directional control without
removing a hand from the steering wheel.
• Optimized stall ratio for torque converter
provides high torque without sacrificing
travel speed.
• A modulating control valve absorbs initial
pressure spikes during initial engagement
and directional change. This improves shift-
ing capabilities and prolongs the life of the
entire drive train.
• Transmission oil is double-filtered by a 125-
micron mesh on pickup, and a 35-micron
cartridge on the return line.
Gasoline, LPG, or Dual-Fuel systems are
available. The gasoline fuel tank is integral to
the truck frame.
• In-tank mounted gasoline fuel delivery
pump, fuel-level sensing unit, pressure
regulator and filter are standard.
• LPG fuel system uses single-point, throttle
body fuel injection. A removable 33 lb.
fuel tank is available with a fold back tank-
mounting bracket.
COOLING SYSTEM
The high-capacity aluminum radiator is
designed with an efficient thermal transfer
fin and integral oil cooler for the transmis-
sion torque converter.
• High-volume cooling fan uses flexible plastic
blades and shroud for maximum air volume
and noise abatement.
• Transmission oil cooler is integral with
the radiator.
• Inching control and auxiliary brake pedal
combination allows the operator precise
truck positioning with positive control.
• Open step in the frame with a traction
surface and a large handgrip provide easy
entry and exit for the operator.
• Standard headlight/turn indicator control
lever is mounted on the steering column
for easy use.
• Full-width overhead guard provides excel-
lent visibility for high stacking and meets or
exceeds ITSDF requirements.
ELECTRICAL SYSTEM
Standard instrument package and operator
conveniences:
• 12-volt electrical system
BRAKES
Hydraulic brakes are self-energizing and
self-adjusting.
• Brake fluid r
eservoir is located under the
console cover for fast, easy inspection and
maintenance.
• Heavy-duty brake backing plate and thick
brake drum provide reliable braking action
and reduced heat.
• Mechanical parking brake has two-stage
latching mechanism for positive engagement.
• 50A alternator with built-in IC regulator
• Key-lock, anti-restart ignition switch
• High-torque, low-amp starter motor with
planetary gear reduction
• Waterproof electrical connectors
• Electric fuel gauge, water temperature
gauge, LCD hour meter
• Indicator lights for Neutral/Return to
Neutral, Low Oil Pressure, Low Battery/
Alternator Output, Check Engine Warning,
Hydraulic Lock (Operator Presence), and
ECCS Status Code
SERVICEABILITY
The engine and transmission can be easily
accessed for daily inspection without the use
of any tools.
• Single-piece, all-steel engine cover and
seat support is fully insulated to reduce
noise and heat transfer.
STEER AXLE
• ECCS Service Support Tool connector for
rapid system diagnostics
Fully Hydrostatic Power Steering is standard.
• Heavy-duty fabricated steer axle has dou-
ble-acting, double-ended power steering
cylinder and no drag links or tie rods.
• Steering stops are machined into the
steering cylinder to reduce stress impact
on steering linkages.
• Engine cover has gas-filled cylinder with
an automatic locking device to assist in
opening and to prevent the cover from
unexpectedly closing.
• Engine cover is shaped for easy access
into the engine area for maintenance
and service.
HYDRAULIC SYSTEM
The Hydraulic System features an integral
reservoir, direct drive gear pump and fully
filtered system.
• Large hydraulic fluid reservoir integral to
the truck frame reduces heat buildup in
the system.
• Load sensing valve in the hydraulic circuit
reduces the flow of oil to the power steer-
ing system when steering wheel is idle.
• Grease fittings on all linkages are acces-
sible without lifting the truck.
COMPLIANCE, APPROVALS AND
ENVIRONMENTAL CONCERNS
Designed for maximum recycling at end
of life, with special attention to materials
and construction. Counterweight designed
for breakup during recycling process.
Transmission case is recyclable aluminum.
MAST, CARRIAGE, LBR AND FORKS
High-visibility mast assembly has a 4-roller
carriage that is available in two-, three-, and
four-stage Free Lift, Free View designs.
• Sealed bearings require no maintenance.
• Angle-mounted bearings and a shaped rail
flange prevent excessive wear and friction,
while maintaining correct side thrust
clearance.
• ITA Class II carriages accept a variety of fork
sizes and common load-handling attachments.
• 48-inch-high load backrest is standard for in-
creased load control and operator protection.
• Single or double auxiliary hydraulic-function
internal hose routing is available.
FRAME
An all-welded assembly with heavy-gauge
steel and integral hydraulic and fuel tanks
provide exceptional durability.
• Welded front cross-member and bolted
drive axle increase frame rigidity.
• Loads are transferred directly from the mast
to the drive axle and onto the floor without
being transmitted through the frame,
reducing frame stress.
Hamech lift trucks meet or exceed
American National Standard Institute,
ITSDF B56.1-Part III Safety Standards for
Powered Industrial Trucks.
Compliant with UL 558 for the appropriate
truck type. Contact your dealer for applica-
tion-specific requirements. Meets or exceeds
current EPA emissions standards.
• Wide, open step is designed into the
frame assembly without compromising the
structure.
OPERATOR COMPARTMENT
A unique suspension compartment isolates
the operator from the floor surface and from
engine vibration, for greater operator
comfort and productivity.
DRIVE AXLE
A heavy-duty, cast steel drive axle housing
supports the load and chassis without placing
a load on the free-floating axle shafts.
A flange is mounted to the truck frame to
improve load distribution and reduce
frame flexing.
