Spearhead gearboxes are recommended to be filled with:
Splitter Gearbox - SAE EP80-90W or GL-4/GL-5 grade oil.
Rotor Gearboxes – 85W-140 grade oil.
Any different or higher SAE grade of oil is not recommended.

Table 5.1 – Multicut Gearbox Oil Capacities
Changing the oil regularly prevents problems associated with deterioration, moisture build up in the oil and the
potential presence of metallic particles which form early in the machines life. Oil changes are recommended on
Multicut machines after the first 50 hours, and then every 500 hours thereafter.
To drain the oil, each of the gearboxes is fitted with a drain plug. With reference to Figures 5.2 (2) and 5.3 (2),
the locations of these drain plugs can vary. If there are facilities to vacuum draw the oil out of the respective
gearbox, the oil can be changed through the fill hole/dipstick location instead which is considerably easier; see
Figure 5.2 (1) and 5.3 (1).
Two techniques are required to be used to check the oil level on the Multicut 300, depending on the gearbox in
question:
• The splitter gearbox utilises a level plug which should be removed and visually inspected to ensure the
oil is up to height of the plug; see Figure 5.2 (3).
• The rotor gearboxes utilises a dipstick which should be removed and visually inspected on the gauge to
ensure the oil is up to level mark: see Figure 5.3 (3).
The gearbox should not require additional lubricant unless the box is cracked or a seal is leaking. It is
recommended that the oil level is checked every day before operation and additional oil added if it’s required.
• On the splitter gearbox, add enough oil to the point where oil is beginning to seep out the level plug; see
Figure 5.2 (3), before proceeding to use the machine.
• On rotor gearboxes add an additional oil if it’s required to bring it up to the upper level mark on the
dipstick, see Figure 5.3 (3), before proceeding to use the machine.
At all times the oil level should be above the lower fill mark; see Figure 5.3 (4) as otherwise permanent
damage could be caused to the gearbox.
