Wear safety glasses and other appropriate
apparel when removing/installing the snap ring or
performing any work with an arbor press. Caution
all onlookers about the possibility of flying debris
and personal injury.

13) Mount the bearing block to the access plate.
Tighten the 3/8 inch self locking hexagon nuts with the
torque wrench to 35 ft lbs (47 Nm.).
14) Install the access plate to the main frame by
aligning the dowel pins and installing the cap screws
and washers. Tighten with the 3/4 inch wrench.
A properly installed replacement bearing should rotate
without excessive friction, drag and/or “rough spots”. If
these symptoms occur after assembly, the bearing was
improperly supported when pressed into the bearing
block. The resulting thrust placed upon the bearing
exceeded its static capacity. A bearing operating with
these characteristics will deliver minimal service life
and be prone to premature failure.
15) If the Surface Planer is powered by an engine,
reconnect the engine spark plug wire. If powered
by an electric motor and the machine is to be used
immediately, reconnect the extension cord or Surface
Planer to the power source. Determine that the oN/
oFF switch located on the operator handle is in the
oFF position.
UNEXPECTED MACHINE START UP CAN RESULT
IN PROPERTY DAMAGE AND/OR PERSONAL
INJURY.
LUBRICATION REQUIREMENTS
Application: SP684 SURFACE SHARK
Parts Required:
1 each, container of dry film lubricant
1) Lubricate the caster wheel bearings with a dry film
lubricant only. Dry film lubricants dry immediately upon
contact. use sparingly. Excess lubricant will attract the
fine grained, powered materials described and directly
affect bearing service life.
Do not lubricate the caster wheels with any type of
grease material. Grease will attract foreign material
accumulations that can accelerate bearing wear.
2) The flail drum driveshaft is supported by extra
capacity, double row ball bearings. both bearings are
of a sealed design and should not require additional
lubrication during their normal service life. The
grease type and amount utilized for the bearings are
intended to provide proper lubrication for the respective
loads and operational speeds. Replacement bearings
should contain approximately 30 percent fill capacity.
Excessive amounts of grease in the bearing cavity can
actually increase friction and resulting heat increases
can also dramatically shorten bearing service life.
3) The hand crank bearing is sealed and should not
require additional lubrication during its normal service
life.
4) Do not apply belt dressing materials to the v-belt for
the purpose of minimizing slippage. These products
typically attract foreign material accumulations that
can accelerate component wear. Excessive v-belt
slippage can be eliminated with proper v-belt tension
and alignment.
5) Loosen the rubber boot to expose the hand crank
screw threads. Lubricate the threads with dry film
lubricant on a regular, scheduled basis. Clean and
remove all material accumulations around the
