Introduction
Thank you for choosing Dragon Equipment. Our crushers are 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.
The CR300 is designed to reduce sections or pieces of concrete, bricks or stones by a crushing action.
The reduction output can be adjusted to produce three different sizes of product (hardcore).
Limitations
•Steel reinforced sections should be avoided.
•Wood (any type), cloth, rubber etc. must not be placed into the crusher's jaws.
•Be aware of these items when encased into the set concrete. They may cause the crushing
action to stop when revealed during the crushing process.
Delivery
All Dragon Equipment CR300 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 crusher. In particular, read pages 6-7 which contain important health and safety
information and advice.
Important Health and Safety Information
Before using your new crusher, please take the time to read this manual.
Failure to do so could result in:
•Personal injury.
•Equipment damage.
•Damage to property.
•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

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.

Basic Crushing Operation Safety
The operator should be aware of the following points:
•Be aware when the crusher is processing material that is an awkward shape. The material
can move in the funnel with great force.
•Never leave the crusher 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.
•Always operate the crusher with the engine set to maximum speed when crushing.
•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.
•Always keep hands, feet and clothing out of the feed opening, discharge and moving parts.
•Keep the discharge area clear from debris build-up.
•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 crusher 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 crusher 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 crusher inside buildings.

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 crusher must also
wear ear protection (EN 352) at all times to prevent possible damage to hearing.
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 crusher 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:
•Fill the fuel tank completely before parking the machine overnight or for extended periods
to prevent 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: 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 all stop buttons.
•Check the action of all E-Stop buttons.

WARNING
Do not use or attempt to start the crusher
without the protective guarding in place.
Failure to do so may result in personal
injury or loss of life.
Starting the Engine
Checks Before Starting
•Ensure the machine is located on firm flat ground.
•Check all guards are fitted.
•Carefully inspect tracks for cuts or other damage.
•Check the chute is clear and there are
no obstructions.
•Visually check for fluid leaks.
•Ensure there is sufficient fuel in the fuel tank.
Do not place engine under full load at full speed immediately after starting. Always allow the engine
to fully circulate lubricant and warm up gradually before operating at full speed and load.
•Ensure that all track levers are in the neutral position.
•Ensure E-Stop buttons are pulled out.
•Press Start Crusher green button once to turn the machine ON. It will then flash.
•Move the throttle control to 1/3 of total movement in direction of GREEN arrow.
•Pull choke control to the full choke position in direction of BLUE arrow.
•Insert key in the ignition and turn clockwise to start the engine.
•If the engine does not crank and the E-Stop LED is flashing the throttle lever is in the OFF
position. Move the throttle lever to 1/3 position and repeat turning the key.
•Release the key as soon as the engine starts.
•NOTE: To extend the life of the starter, use only short starting cycles - 5 seconds max.
•Push the choke control to the off position soon after starting. Normally with 1-2 seconds
•Allow the engine to warm up.
NOTE: After start crusher button is pressed the machine must be started within 20
seconds else it will switch OFF.
