Tufner T918 - User Manual

The T918 Electric Pallet Truck (Scale) is a battery-powered industrial vehicle designed for efficient and safe material handling. It utilizes an AC drive system for electric driving and lifting, offering characteristics such as labor-saving operation, lightweight design, high efficiency, smooth movement, simple operation, safety, reliability, low noise, and no pollution.

Function Description:

The primary function of this electric pallet truck is to transport and lift palletized goods, with an integrated scale for weighing. Its main weighing functions include zeroing, tare function, accumulation, unit exchange (between Kg and Lb), checkweighing, and battery voltage indication. It also features auto power off and power saving functions. The scale instrument displays the current weight after self-checking and allows for zero setting within an allowable range. The accumulation function allows for summing multiple weighing data, displaying "n001" for the first weight and incrementing up to "n999" after cyclic operations. Printing of the current weight is possible when the data is stabilized.

Usage Features:

The pallet truck is equipped with an emergency stop switch for immediate power cut-off, located on the top of the vehicle body. A password lock function prevents unauthorized operation, with a factory default password of 1234 for operation and 3232 for administrator access. The handle display shows battery charge indication, with 10 cells representing 10% power each. The last two cells flashing indicate a low battery needing charge.

Driving and braking are controlled via the handle, which has three vertical areas (A, B, C). Moving the handle to area A or C activates emergency braking, while area B allows for normal travel. Regenerative braking is activated by returning the gas pedal knob to the 0 position or releasing it. The gas pedal knob controls driving speed in forward (FW) or backward (BW) directions. A "turtle speed" mode allows for slow-speed driving, activated by a dedicated button. An emergency reverse switch on the handle prevents the operator from being crushed by slowing down and reversing the vehicle.

The vehicle's direction is controlled by turning the handle left or right. Up and down switches on the tiller control fork movement, and a horn button is also present.

Maintenance Features:

• Battery Care: Timely charging is crucial to ensure the battery is in a full state of charge and to prevent excessive discharge, which can damage the battery. Regular checks of connection parts and terminal surfaces are recommended for good contact. When cleaning the battery surface, use a dry cloth and fiber wipe to prevent static electricity and explosions. Metal conductive objects should not be placed near battery terminals to avoid short-circuiting. Battery short-circuit firing should not be used to check power. For long-term storage, the battery should be fully charged, disconnected from the negative wire, and stored in a dry, frost-free place, with monthly balancing and replenishment. Only the included charger should be used.
• Daily Inspection: Before use, operators should check for hydraulic pipeline oil leakage, intact and normal wheels, and absence of jamming. Faulty vehicles must not be used.
• Fault Codes: The manual provides a comprehensive list of fault codes (e.g., 20E002 for short circuit/overcurrent, 20E007 for high temp, 20E012 for overload) along with their possible causes and corresponding solutions, which often involve checking connections, replacing components, or adjusting operating conditions.
• General Maintenance: The vehicle is suitable for indoor use on hard, flat ground, avoiding slopes, uneven surfaces, bumpy pits, and gravel. It should not be used in corrosive, flammable, explosive, or acid/alkali environments, or in environments with large temperature differences. Overloading is strictly prohibited, as is placing heavy objects on forks in a hurry. Cargo should be stable and centered between the forks. Sharp turns in narrow passages should be avoided, and the forks should be lowered to the lowest position when not in use. It is strictly forbidden to place any body part under heavy objects or forks. The vehicle socket should be protected from rain, and any water intrusion should be promptly wiped clean. Operation below low voltage is prohibited. Direct connection to external AC power is forbidden unless a built-in charger is present. Untrained personnel are strictly prohibited from operating or repairing the electric pallet truck.
