Changing the Gearbox
Lubrication
Service Interval: After the first 8 hours
Every 250 hours
The gearbox is filled with 80W-90 gear oil or
equivalent.
1.
Clean debris from the fill plug and the drain cap
to avoid contamination
2.
Remove the fill plug to relieve air draw.
3.
Position a drain pan under the drain tube and
remove the drain cap.
Note:
The high viscosity of cool oil extends the
drain time (approximately 30 minutes).
4.
After oil is completely drained, install the drain
cap.
5.
Fill the gearbox with 1650 ml (56 fl oz) of high
quality 80W-90 gear lube.
6.
Install the fill plug.
7.
Check the oil level.
Checking the Coring Head
Fastener Torque
Service Interval: After the first 8 hours
Every 250 hours
After the initial 8 hours of use, check the coring head
fasteners to ensure that proper torque is maintained.
Fastener torque requirements are listed on the
reference service decal below and located on the
coring head.

Inspecting the Belts
Service Interval: Yearly
The drive belt(s) on the machine are durable.
However, the normal exposure to UV radiation, ozone
or incidental exposure to chemicals can deteriorate
the rubber compounding over time and lead to
premature wear or material loss (i.e. chunking).
Annual belt inspection is highly recommended for
signs of wear, excessive cushion cracks, or large
embedded debris with replacement when needed.
Adjusting the Belt Tension
Service Interval: Before each use or daily
Make sure that the belt is properly tensioned to ensure
correct operation of the machine and to prevent
unnecessary wear.
1.
Check for proper belt tension by compressing
idler spring to a length of 146 mm (5-3/4 inches);
refer to
Figure
1. Spring length
2. Stored energy hazard—read the Operator's Manual.
3. Entanglement hazard, belt—stay away from moving parts.
2.
Adjust the belt tension as follows:
A.
Remove the rear coring head cover
