Crushing
The CR300 has an electronic monitoring device to ensure the engine is kept at the optimum
operating speed known as No-Stress. A product that has a harder density will automatically be
detected and select a different operation mode until the greater load has passed. A product that
requires a greater breaking force than the crusher can apply will automatically activate the Anti-Stall
function and turn off the jaw movement so as not to stall the engine.
Crushing Controls
Crusher Mode Button
Start crusher - Activates continuous forward movement by pressing once.
Stop crusher - Stops forward movement by pressing once.
Reverse - Activates momentary reverse (when the button is released the reverse action
stops).
E-Stop

Troubleshooting
•The machine will not track:
oThe mode selector is set to Crush –Set switch to Track Mode.
oRock jammed into drive sprocket –change direction and remove the loose rock.
•Crushing jaws will not start moving:
oThe crusher is jammed –refer to blockages section below.
oThe mode selector is set to Track –Set switch to Crusher Mode.
oThrottle control is set to a slow speed –ensure the lever is fully across.
•Crushing jaws start and stop erratically:
oThrottle control is set too slow speed –ensure the lever is fully across.
•The engine will not crank to start:
oEnsure all E-Stops are in the off position. No LED red light showing.
•The engine will crank, but not start:
oEngine too hot –Turn off choke as not required.
oEngine too cold –Turn on choke as required.
oNo fuel in the tank –Check level and fill as required.
oWrong fuel has been poured into the tank –Drain fuel from tank and carburettor
and replace with the correct grade of petrol.
Blockages
A blockage or jam can be caused by:
Material jammed in the funnel.
Overfeeding material or oversized material.
A foreign body in the crusher funnel such as wood or metal.
Excessive wet soil, clay etc.
Continuing to feed material into a blocked machine may cause damage to the machine, if the
crusher becomes blocked, proceed as follows:
Use the Blue Reverse button to inch the jaws backwards and forwards, which in most cases
will shift the product and cause it to drop deeper into the jaws, so allowing the crushing
process to continue.
If this action does not have the desired effect. Stop the engine immediately.
While wearing gloves remove the majority of the debris causing the blockage.
Restart the engine and increase to full speed.
Press the Green Start Button to continue, repeat the reverse action as required.
Allow machine time to clear any excess material still remaining before you continue feeding.

Service Instructions
Safe Maintenance
While carrying out maintenance, handle the crusher's
components with care to avoid injury, it is recommended
that gloves are worn while carrying out servicing to
minimise the risk of contact with hazardous materials. The
major components of this machine are heavy and if
required, lifting equipment should be used.
Safe Lifting and Securing of the Crusher
If the crusher cannot be driven onto its transport vehicle,
a hoist can be used. The lifting points are designed to lift
only the machine’s weight. Always inspect the lifting bar
prior to each use and do not use if damaged. Maximum
lift weight is as indicated on the machine data plate.
The method of securing the crusher can vary depending on the type of carrier and position of tie-
down points available on the carrier. It is recommended that correctly rated ratchet straps are used
to secure the machine via the track frame or over the tracks to the carrier lashing points. This must
be carried out by competent qualified personnel. Failure to secure the load correctly could result in
chassis and/or undercarriage damage or loss of load.
Lubrication and Servicing
Lubrication is an essential part of preventive maintenance. It is important that the instructions
regarding types of lubricants and the frequency of their application be followed to prolong the life of
the machine. Periodic lubrication of moving parts helps prevent the possibility of mechanical
failures. Thoroughly clean all fittings, caps, plugs etc., to prevent dirt from entering the system while
servicing. Lubricants must be at operating temperatures when draining.
Do not operate any system unless oil level is within the operating range as indicated on the dipstick,
level plug or sight glass. All change and service periods are recommendations based on average
operating conditions. Lubricants showing evidence of excessive heat, oxidation or dirt should be
changed more frequently to prevent these conditions. Lubricants change and service periods must
be established on the basis of individual job conditions.
Recommended Lubricants
Engine - Vanguard ® Synthetic 15W-50
Hydraulic - VG32 Mineral Oil
Grease Nipples –Shell Gadus S3 V100 premium multi-purpose grease
Spares
Only fit genuine Dragon Equipment crusher spares. Failure to do so will result in the invalidation of
the warranty and may result in damage to the crusher, personal injury or even loss of life.
WARNING
Always immobilise the machine before
undertaking any maintenance work on the
crusher by removing the ignition key and
disconnecting the battery. Ensure the
crusher is stable and on level ground
before performing any maintenance.

Engine Servicing
All engine servicing must be performed in accordance with the Engine Manufacturer’s Handbook
provided with the machine.
NOTE: Failure to adhere to this may invalidate the warranty and/or shorten engine life.
Hydraulic Hose Check
All the hydraulic hoses should be regularly inspected for chafing and leaks. The hydraulic system is
pressurized to 150 Bar (2175 PSI) and the hoses must be kept in good condition. If any hydraulic
components are changed, new seals should be installed during reassembly. Fittings should then be
retightened.
