5. Repeat steps 3 and 4 at the other side of the
cover.
Lubrication
Checking the Coring Head
Bearings
Service Interval: Yearly—Check the coring head
bearings.
Every 500 hours—Inspect the coring head
bearings, if needed, replace.
The machine has no grease fittings that must be
lubricated.
Important:
Bearings rarely fail from defects in
materials or workmanship. The most common
reason for failure is moisture and contamination
working its way past the protective seals.
Bearings that are greased rely upon regular
maintenance to purge harmful debris from the
bearing area. Sealed bearings rely on an initial
fill of special grease and a robust integral seal to
keep contaminants and moisture out of the rolling
elements.
The sealed bearings require no lubrication or short
term maintenance. This minimizes routine service
required and reduces the potential of turf damage
due to grease contamination. These sealed bearing
packages provide good performance and life under
normal use, but periodic inspections of bearing
condition and seal integrity should be conducted to
avoid downtime. Inspect the bearings seasonally
and replace them if they are damaged or worn.
Bearings should operate smoothly with no detrimental
characteristics such as high heat, noise, looseness,
or rust weeping.
Due to the operating conditions these bearing/seal
packages are subject to (e.g., sand, turf chemicals,
water, impacts, etc.) they are considered normal wear
items. Bearings that fail due to causes other than
defects in materials or workmanship are typically not
covered under warranty.
Note:
You can negatively affect bearing by using
improper wash down procedures. Do not wash down
the machine when it is still hot and avoid directing
high-pressure or high volume spray at the bearings.
It is common for new bearings to purge some grease
out the seals on a new machine. This purged grease
turns black in color due to collection of debris and not
due to excessive heat. It is good practice to wipe this
excess grease from the seals after the initial 8 hours.
There may always appear to be a wet area around
the seal lip. This is not detrimental to bearing life, and
keeps the seal lip lubricated.
