Introduction to GPTWR Operation

This section explains why following proper operating procedures matters and how the system is designed to function.

Operating a tuck under liftgate like the Maxon GPTWR requires strict adherence to sequence and safety practices. Incorrect operation can result in serious personal injury or equipment damage, especially when working around moving hydraulic components (Maxon GPT Series Operation Manual, p. 6).

Operators must:

• Follow all instructions and warning decals
• Use the control switch correctly
• Maintain awareness of surroundings during operation

Standing to the side of the platform and keeping the operating area clear are critical safety requirements during all liftgate movements (Maxon GPT Series Operation Manual, p. 6).

Pre-Operation Setup

This section outlines the required setup before beginning any liftgate operation.

Before operating the tuckaway liftgate, ensure the vehicle and environment are properly prepared.

Vehicle Positioning

• Park on level ground
• Set the parking brake
• Ensure the vehicle is stable before operating the liftgate (Maxon GPT Series Operation Manual, p. 8)

Area Awareness

• Verify the area is clear of people and obstacles
• Consider nearby traffic or hazards when operating roadside
• Be aware of surrounding traffic and hazards when operating near roadways (Maxon GPT Series Operation Manual, p. 17)

Equipment Readiness

• Ensure the control switch is functional
• Confirm the platform area is clear
• Make sure no part of the body is positioned near moving components

Operators should never allow untrained personnel to operate the liftgate and must always maintain full control during operation (Maxon GPT Series Operation Manual, p. 6).

Step-by-Step Liftgate Operation

This section provides the full operational workflow for the Maxon GPTWR operation process.

Step 1: Activate the liftgate by pressing the UP switch for approximately 2 seconds

• Stand to the side of the platform
• Push the toggle switch to the UP position for approximately 2 seconds (Maxon GPT Series Operation Manual, p. 20)

This activates hydraulic pressure and prepares the system for movement.

Step 2: Lower the Platform to the Ground

• Use the control switch to lower the platform until it contacts the ground

Once grounded, the platform is ready to be unfolded (Maxon GPT Series Operation Manual, p. 20).

Step 3: Unfold the Platform

• Manually unfold the platform
• Do not operate the control switch while unfolding (Maxon GPT Series Operation Manual, p. 20)

This ensures safe deployment without unintended movement.

Step 4: Unfold the Flipover

• Manually unfold the flipover section from the platform (Maxon GPT Series Operation Manual, p. 21)

The flipover provides a smooth transition between ground and platform.

Step 5: Raise and Lower the Platform

• Push toggle switch to UP to raise the platform
• Push toggle switch to DOWN to lower the platform
• Release the switch at any time to stop movement (Maxon GPT Series Operation Manual, p. 21)

The liftgate uses hydraulic power to raise and lower the platform.

Step 6: Control Switch Operation

• The toggle switch controls all lift functions
• Movement occurs only while the switch is engaged
• Releasing the switch immediately stops the platform (Maxon GPT Series Operation Manual, p. 21)

Loading and Unloading Procedures

This section explains correct load handling techniques for safe operation.

Ground-Level Loading

• Load cargo onto the platform while it is on the ground
• Ensure the load:
• Does not extend past platform edges
• Is stable and secure (Maxon GPT Series Operation Manual, p. 22)

Bed-Level Loading

• Raise the platform to vehicle bed height
• Move the load into the vehicle body (Maxon GPT Series Operation Manual, p. 22)

Proper Load Positioning

• Always position loads:
• As close as possible to the inboard edge
• With the heaviest portion toward the vehicle body (Maxon GPT Series Operation Manual, p. 23)

This ensures proper balance and prevents instability.

Safe Operator Positioning

• Stand to the side when operating
• If standing on the platform:
• Keep feet clear of edges
• Remain within the designated footprint area (Maxon GPT Series Operation Manual, p. 22)

Unloading Best Practices

• Avoid pulling loads onto the platform, as this increases the risk of falls and injury
• Pulling loads increases risk of falls and injury (Maxon GPT Series Operation Manual, p. 23)

Using the Maxon GPTWR Walk Ramp (If Equipped)

This section covers the operation of the optional walk ramp feature.

The Maxon GPTWR walk ramp allows operators to move cargo directly between the ground and the vehicle without raising the platform.

• The walk ramp feature is only available on properly equipped models and must be used according to Maxon’s operating instructions and safety guidelines.
• Operators must follow manufacturer-specific instructions
• All applicable warnings and safety precautions must be followed (Maxon GPT Series Operation Manual, p. 18)

Proper Stowing Procedure

This section explains the correct sequence for stowing the liftgate after use.

Step 1: Lower Platform to Ground

• Ensure all loads are removed
• Lower platform fully to the ground (Maxon GPT Series Operation Manual, p. 24)

Step 2: Raise Platform Slightly

• Raise the platform approximately 2 inches above ground (Maxon GPT Series Operation Manual, p. 24)

Step 3: Fold Flipover

• Manually fold the flipover onto the platform
• Ensure cart stops are stowed (if equipped) (Maxon GPT Series Operation Manual, p. 25)

Step 4: Fold Platform

• Fold the platform under the extension plate
• Keep hands clear of moving components (Maxon GPT Series Operation Manual, p. 25)

Step 5: Raise to Stowed Position

• Push toggle switch to UP
• Raise liftgate fully and hold briefly
• Liftgate must be stowed under hydraulic pressure (Maxon GPT Series Operation Manual, p. 26)

Critical Reminder

• Never move the vehicle unless the liftgate is fully stowed (Maxon GPT Series Operation Manual, p. 6)

Critical Operating Safety Rules

This section highlights essential safety rules that apply throughout all operations.

Operator Positioning

• Always stand to the side of the platform
• Never stand under a moving liftgate (Maxon GPT Series Operation Manual, p. 6)

Clearance and Awareness

• Keep hands, feet, and body clear of:
• Platform edges
• Moving arms and hinges (Maxon GPT Series Operation Manual, p. 6)

Load Safety

• Never exceed rated capacity
• Keep loads stable and within platform boundaries (Maxon GPT Series Operation Manual, p. 6)

Operational Control

• Release the control switch immediately in emergencies (Maxon GPT Series Maintenance Manual, p. 9)

Additional Safety Guidelines

• Do not allow untrained operators
• Do not use forklifts on the platform (Maxon GPT Series Operation Manual, p. 16)

Conclusion

Operating the Maxon GPTWR correctly requires following a clear, repeatable sequence—from setup and deployment to loading, unloading, and proper stowing. By adhering strictly to manufacturer procedures and safety guidelines, operators can ensure consistent performance and reduce operational risk.
