Gravel/Maintenance & Lubrication

WARNING

NEVER POUR OR SPRAY WATER ON
THE MOTOR.

NEVER PLACE HANDS OR ANY
OBJECT INTO THE DRUM WHILE
THE MOTOR IS RUNNING.

ALWAYS DISCONNECT THE

7. Slowly add 4 shovels full masonry sand

Note: Water will vary according to moisture

content of sand and gravel

MAINTENANCE and LUBRICATION

To get long and trouble-free service from this mixer,
it is essential that you perform periodic maintenance.

Adjust belt as required by loosening the (4) motor
mount bolts and moving motor as necessary.
Retighten these bolts after adjustment. The belt
should deflect approximately 1/4 inch at the halfway
point when 5-10 lbs of pressure is applied.

Adjust pinion/gear mesh as required by loosening
the two (2) pinion jackshaft bolts and moving
jackshaft as necessary. Retighten these bolts after
adjustment.

Grease after each use through the (2) fittings
provided. Use any Grade #1 lithium based grease.
DO NOT grease or oil the gear. This will attract
sand and cause excessive wear.

PEDESTAL MODEL ASSEMBLY

WARNING

WHENEVER ASSEMBLING,
LUBRICATING OR ADJUSTING ANY
PART OF THE MIXER, DISCONNECT
THE POWER PLUG.

To attach motor (6) to frame assembly (4), line up
motor to match the four holes on the side motor
mount. Attach the V-belt (8) to the motor pulley (7).
Using the four 5/16 x ¾ in Hex Flange Screws (31)
and four 5/16 Hex Flange Lock Nuts (32), secure
the motor in place. The V-belt should be tightened
until the belt deflects approximately ¼ in when 5-10
pounds of force is applied centrally between the
pulleys. Assemble base legs (1 and 2). Assemble
Yoke (3) to assembled base and pin (29). Using two
people, lift and place Frame Assembly (4) onto Yoke
(3) pivot pins and insert pins (26). Slide dump
handle Grip (19) over the end of the Dump Handle
(18) and insert the Handle in the Frame Assembly
(4).

GREASE

25CMPT Pedestal Assembly

WARNING

KEEP HANDS AND CLOTHING
AWAY FROM MOVING JACKSHAFT
AND GEAR.

Place Thrust Washer (25) onto Drum Shaft (15) and
lightly grease the shaft. Using two people, carefully
slide the Drum assembly with shaft into the tube
located centrally on the Frame (4). Check to see that
the Jackshaft Gear (10) is properly meshing with the
Drum Main Gear (14). Place locking Collar (17)
onto Shaft (15) and tighten setscrew.

Grease the Fitting (24) on the Drum Shaft tube until
grease appears near the locking Collar (17) and the
Thrust Washer (30).

Check the clearance of Gear Guard (21) and the
Drum (5) to make sure there is no contact between
the rotating Drum and the Guard.

LUBRICATION

Any grease fittings (Item 24) require an application
of any type EP grease after each use. Apply grease
until grease begins to come out of the bushings.
Lubricate before each use of the mixer.

Using a grease gun, apply grease to the Fitting (24)
on the Jackshaft Tube if not already greased at
factory. Plug in the Power Cord. Let the motor run
for about 5 to 8 minutes, then turn off motor. This
will break-in the jackshaft bushings.

legs to join together. (Figure 1)

2. Insert locking pin through bottom of pivot tube.

Attaching Pedestal Stand to Mixer

1. Tip mixer, as if dumping contents, and place
squarely on opening of drum. The pivot
mount plate will rotate freely about the wheel
axle from its wheelbarrow stowed position.
(Figure 2)

2. Rotate pivot mount plate away from drum and
onto frame stop. Back off thumbscrew to
allow clearance for inserting pivot tube on
stand through tube. (Figure 3)

WARNING

Pivot mount plate will rotate freely about
axle when tipping mixer onto opening of
drum. Stand clear of wheel axle or
personal injury could occur.

5. Once mixer has been tilted upright onto the
stand, the mixer should be tipped back into
mixing position before operating.
(Figure 6)

WARNING

Do not tilt mixer upright onto stand on
a wet, uneven or slippery surface.
Failure to follow this instruction could
result in personal injury or damage to
equipment.

4. Once the stand has been attached, move to
the opening side of the drum and begin
tilting the mixer upright onto the stand.
Always bend your knees and use correct
posture for lifting. Always tilt from the
front of the mixer. (Figure 5)

Converting unit back to Wheelbarrow
from Stand

To convert unit back to wheelbarrow operation
follow the directions for assembling and attaching
the pedestal stand to the unit in reverse. Make
sure to tighten thumbscrew and rotate the pivot
mount plate about the axle to its wheelbarrow
stowed position before using the unit in its
wheelbarrow function. (Figure 7)
