Introduction
Thank you for choosing Dragon Equipment. Our Lifting Machinery is designed to give safe and
reliable service if operated in accordance with the instructions which are provided as a guide to
familiarise the operator with the controls, inspections, start-up, operating, and shutdown
procedures.
Limitations
The LF750 Lifter is designed to lift and transport up to 750 kg with the user operating the
machine from the platform.
A maximum unloaded tracking angle of 20°.
When loaded, only operate or tracked on level and stable ground.
Delivery
All Dragon Equipment LF750 Machines have a full pre-delivery inspection before leaving the factory
and are ready to use. Read and understand this instruction manual before attempting to operate or
move the lifter. In particular, read pages 4-8 which contain important health and safety information

Important Health and Safety Information
Before using your new lifter, please take the time to read this manual. Failure
to do so could result in:
Personal injury.
Equipment damage.
Property damage.
Third-party injuries.
The machine must be properly operated and maintained to keep it in a safe
and efficient functioning condition. Ensure that all controls are free of mud,
grease, or other matter that might cause slips hazardous to the operator or
other personnel. Report all malfunctions to those responsible for maintenance
or site safety. Do not operate the equipment until corrected. Normal service

Safe Working
Operator’s Personal Protective Equipment (PPE)
Suitable work gloves.
Steel toe cap safety boots complying with ISO 20345:2011.
Appropriate close-fitting clothing.
Never wear loose clothing, rings, and watches etc. that might catch the controls.
High-visibility clothing complying with ISO 20471:2013 if required.
Eye, Head and Eye Protection if required.
Basic Operation Safety
The operator should be aware of the following points:
Ensure lifter tilt angles are within limits when transporting material on uneven ground.
Never leave the lifter unattended when in operation or with the engine running.
If an accident occurs, stop the machine, remove the key and call the emergency
services immediately.
General Safety Matters
Always ensure the engine has stopped and cooled down before making any adjustments,
undertaking maintenance, refuelling or cleaning.
Always ensure there is no risk of the machine moving during operation. Be aware of slope
inclines and surface conditions.
If there are any fluid leaks, cease operating the machine, stop the engine and repair
before continuing.
Take regular breaks, do not operate the machine when tired.
Ensure protective guards are in place before operating machine. Failure to do so may result
in personal injury or loss of life.
Always operate the lifter in a well-ventilated area to prevent the build-up of
exhaust fumes.
Ensure a fire extinguisher is available on site.
Ensure a personal first aid kit is available and know its location.
Do not operate the lifter in low light levels and be aware of changeable weather.
Do not smoke when refuelling.
Do not allow individuals to operate the machine who have not been trained.
Do not climb onto the machine.
Do not touch exposed wiring due to the risk of electric shock.
Do not use the lifter inside buildings without sufficient ventilation.

Engine Noise
Noise levels above 80dB (A) will be experienced at the working position. Prolonged exposure to loud
noise may cause permanent hearing loss. All persons within close vicinity of the lifter must also wear
ear protection (EN 352) at all times to prevent possible hearing damage.
The average sound pressure level at one metre for the Vanguard 400 is:
3600FL
[dBA]
3600NL
[dBA]
3000FL
[dBA]
3000NL
[dBA]
96.8
93.8
94.4
90.4
While operating the lifter ensure that all individuals comply with the Control of Noise at Work
Regulations 2005 (Noise Regulations 2005) to prevent or reduce risks to health and safety from
exposure to noise at work.
Refuelling
Follow standard Health and Safety practices.
Stop the engine and allow to cool.
Never smoke or permit naked flames nearby.
Store fuel away from any ignition sources.
Fuel storage containers must be approved, clearly display appropriate labels and have
securely fitting caps.
Use a funnel when refuelling and ensure fuel cap is refitted securely.
Avoid skin contact with fuel. If it gets into eyes wash out with sterile water immediately and
seek medical advice as soon as possible.
Always clean up after any spillages and change clothes if appropriate.

Operating Instructions
Storage and Parking
When parking the machine overnight, or for an extended period, the following procedure in addition
to that given in ‘Stopping the Engine’ will help maintain it in good condition for subsequent use:

condensation.
Always park on level ground where possible. If it must be parked on a slope, position
machine at right angles to the slope and block tracks securely.
Remove the key to a place of safety.
NOTE: Always park the machine with the auxiliary attachment in contact with the ground.
NOTE: Ensure the equipment cannot be started or used by unauthorised or
untrained personnel
To recommission after storage the following checks must be carried out:
Check all fluid levels.
Check for fluid leaks.
Check the tension of rubber tracks.
Check operation of all controls.
Check the action of the Stop Lever.
Check the action of all E-Stop buttons.
