Service Instructions
Safe Maintenance
While carrying out maintenance, handle the LF750 Lifter
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 LF750 Lifter
If the LF750 Lifter 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 before use and do not use if damaged.
Maximum lift weight is as indicated on the machine data plate.
The method of securing the LF750 Lifter 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. The instructions regarding types of
lubricants and the frequency of their application must 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 based on individual job conditions.
Recommended Lubricants
Engine - Vanguard ® Synthetic 15W-50
Hydraulic - VG32 Mineral Oil
Grease - Shell Gadus S3 V100 premium multi-purpose grease
Spares
Only fit genuine Dragon Equipment LF750 Lifter spares. Failure to do so will result in the invalidation
of the warranty and may result in damage to the lifter, personal injury or even loss of life.
