Crushing
•Always position the machine on a level firm surface for loading and ensure the loading area
is clear from slips and trips. When crushing the engine speed must be set to maximum by
pulling the throttle level all the way to the LH side of the engine as shown in Figure 4.
•Ensure the funnel and jaw opening is free from objects not intended for crushing.
•Normal operation can be started by pressing the Green push button on either of the Control
Panels. Before feeding material into the machine ensure it is running smoothly with no fluid
leaks or unusual noises. Product up to the recommended size can then be fed into the
machine. Place it onto the machine funnel and allow to drop into the jaw opening.
•Never place your hands or any part of your body into the crushing jaws with the jaw moving.
•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.
•Using the Blue Reverse and Green forward buttons to inch the jaws backwards and forwards
will usually crush the product and normal processing can continue.
•When this action fails to clear product, with the jaws STOPPED remove the product
and discard.
Adjustment of Crush Size
•Remove outer retaining outer bolt with a 17mm spanner.
•Leave inner bolt and arm fitted to the pin.
•Knock pin from opposite side to release and remove.
•Use retaining arm to turn pin back and forth to allow removal.
•The Lower hole is for Medium crush size. This is the most common size used.
•The Upper hole is for the Largest and Smallest crush size.
•Swing in or out the lower section of the fixed jaw to align the hole to the desired crush size.

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 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
Continuing to feed material into a blocked machine may cause damage to the machine, if the
crusher becomes blocked, proceed as follows:
•Using the Blue button reverse the jaw action, 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.

Check Fittings
The Dragon Equipment CR300 is subject to large loads during its normal course of operation.
Therefore, there is a possibility that nuts, bolts and other fastenings can lose their torque over time.
It is vital that checks are made at regular intervals to ensure the security of these fasteners by using
a torque wrench to the required torque (see below).
NOTE: Uncalibrated torque wrenches can be inaccurate by as much as 25%. It is therefore essential
that a calibrated torque wrench is used to achieve the tightening torques.

Battery Safety Information
The rechargeable Li-Ion polymer battery located under the engine bonnet is a sealed unit which is
not hazardous when used according to the recommendations of the manufacturer. Under normal
conditions of use, the solid electrode materials and Gel electrolyte they contain are non-reactive
provided the battery integrity is maintained.
Safety advice
•Keep out of reach from children.
•Keep away from moisture.
•Do not breathe dust.
•In case of contact with eyes, rinse immediately with plenty of water for 15 minutes and seek
medical attention.
•Wear safety goggles or glasses with side shields if handling a leaking or ruptured battery.
•Use Viton rubber gloves and rubber apron if handling a leaking or ruptured battery.
•Skin Contact: Washing immediately with water and soap.
•Inhalation of Vented Gas: Remove to fresh air. Get medical attention.
•Ingestion: Get medical attention immediately.
Fire and Explosion Data
Extinguishing Media: Dry chemicals, water.
Fire-Fighting Procedures: Use self-contained breathing apparatus and protective clothing.
Unusual Fire and Explosion Hazards: Toxic gases (HF, PF6) will be formed if cells or battery are
involved in a fire. Cells or battery may flame or leak potentially hazardous organic vapours if exposed
to excessive heat, fire or over-voltage conditions. Damaged or opened cells or batteries may result in
rapid heat and the release of flammable vapours.
Storage and Handling / Use
•Do not store batteries in a manner that allow s terminals to short circuit.
•Do not place batteries near heating sources, nor exposed to direct sunlight for long periods.
Elevated temperatures can result in reduced battery service life.
•Charging Battery. Use only approved chargers and procedures. Improperly charging a cell or
battery may cause the cell or battery to flame or damage.
•Battery Disassembly. Never disassemble a battery. Should a battery unintentionally be
crushed, thus releasing its contents, rubber gloves must be used to handle all battery
components. Avoid inhalation of any vapours that may be emitted.
•Battery Short Circuit. Do not short-circuit a battery. A short circuit can result in over-heating
of the terminals and provide an ignition source. More than a momentary short circuit will
generally reduce the cell or battery service life and can lead to ignition of surrounding
materials or materials within the cell or battery if the seal integrity is damaged. Extended
short-circuiting creates a high temperature in the cell and at the terminals. Physical contact
with high temperatures can cause skin burns. In addition, extended short-circuit may cause
the cell or battery to ignite.
•Avoid reversing cell polarity within a battery assembly. Reversing cell polarity may cause the
cell or battery to flame or to emit gases.
