5 Maintenance
WARNING! Before proceeding to carry out any maintenance on SR460/620/820 machines, ensure
that you have thoroughly read and understand Section 2.4 “Safe Maintenance” with regards to the
correct and safe maintenance procedures of looking after the machine. This section gives safe guidance
to ensure the wellbeing on the maintenance personnel as well as the machine itself.
5.1 Periodic Maintenance
Perform service, repairs, lubrication and maintenance procedures outlined throughout Section 5 to ensure the
longevity and reliability of the SR460/620/820 machine.
In general:
5.1.1.1 Inspect for loose or missing fasteners, worn or broken parts, leaky or loose fittings, worn bushes and
any other moving parts which are worn or missing.
5.1.1.2 Replace any worn or broken parts with genuine McConnel parts under the guidance of the specific
section stated in Section 5.
5.1.1.3 Lubricate the machines specified by the lubrication schedule as stated in Section 5.2.
5.1.1.4 Never lubricate, adjust or remove material while it is running or in motion.
5.1.1.5 Torque all bolts and nuts to the settings specified in Section 5.9.
5.2 Lubrication & Greasing
CAUTION! When working with/checking the hydraulic system on the machine always wear safety
glasses and impenetrable gloves. This also applies when working with gearboxes and gearbox oil. Use
paper or cardboard to search for leaks and not hands or any other body parts.
CAUTION! Keep hands and body away from pin holes and nozzles ejecting hydraulic fluid. Ingested or
penetrated hydraulic fluid in the body can become gangrenous. Removal must be carried out
professionally by a suitable Doctor.
The mechanical components of the machine in use must be lubricated to avoid wear and heat build-up.
Lubrication may be through the use of grease or oil. Oil allows higher relative speeds of items such as
gearboxes, whereas grease is generally used to lubricate items such as bearings or bushes. In both cases it is
important to ensure lubrication is given to these various items to ensure their longevity and reliability in use.
5.2.1 Gearboxes
Equipment Required
 SAE EP80-90W or GL-4/GL-5 oil (for splitter gearbox)
 85W-140 (for rotor gearboxes)
 19mm hex spanner (dipstick for splitter gearbox)
 24mm hex spanner (drain for splitter gearbox)
 6mm allen head socket/key (drain for centre/wing gearbox)
The gearboxes have been filled to the correct quantities prior to shipment. However, the oil level should be
checked on the dipstick before operating the machine for the first time and regularly thereafter. It is
important to fill and maintain the gearboxes with the correct quantities of oil. Overfilling the gearbox with oil does
not improve lubrication and may cause overheating. Using an under filled gearbox can cause overheating and
premature wear to components such as seals.
