8.2.4 Oil change intervals
The correct oil level should be checked weekly or every 100 operating hours. If the oil is dirty, burnt or viscous,
change the oil immediately and, if necessary, ush out the gearbox.
Under normal operating conditions we recommend changing the oil every 10,000 hours. The intervals should not
be more than 2 years. Shorter oil change intervals (every 3,000 - 5,000 hours) increase the operating life.
It is also very advisable to change the oil after the rst 500 hours.
The recommendations above may be changed under other operating conditions such as high temperature, high
humidity or a corrosive environment. If one of these situations applies, the oil must be changed more frequently.
9. Inspection and maintenance work
9.1 Topping up grease lubricated gearboxes
Unscrew the lubrication control screw on the housing and, using a grease gun, top up the grease via the grease
nipple on the ange on the drive side or on the motor ange.
Top the gearbox up slowly during operation to ensure that the lubricant circulates properly.
At each top up about a third to a half of the quantity of grease in the table in Section 8.1.2 must be topped up for
the rst stage. If too much grease is used the lubricant may heat up to an unacceptable extent when the machine
warms up or grease may get into the motor or may leak because of excess pressure.
Wipe the excess grease o the lubrication control screws and dispose of properly.
9.2 Checking the oil level
The oil level can be checked on the oil level indicator.
With horizontally installed gearboxes the oil level indicator is normally located on the right hand side of the ge-
arbox, viewed from the drive shaft. As the oil level indicator can be tted both on the left and the right hand side,
the best side for reading it must be selected.
During operation the lower mark on the oil level indicator is considered the guide for the normal oil level. Imme-
diately after start up the oil level may fall below the red mark. However, this is not important as the oil level will
go up again when the oil viscosity goes down as a result of the unit warming up.

9.3 Checking the oil
· Switch the gear motor o and ensure that it cannot be turned on again accidentally.
· Wait until the gearbox has cooled down - Risk of burning.
· Remove some oil from the oil drain plug.
· Check the composition of the oil.
· Check the viscosity.
· If the oil appears to be very dirty on visual inspection, it is advisable to change the oil outside the maintenance
intervals set out in Section 8.2.4 "Oil change intervals".
The oil sample removed must be disposed of properly.
