CLUTCH

GENERAL

The Essick EM-700 and EM-900 Series plaster and mortar
mixers are quality mixers that have a batch capacity of 2.5 and

3.5 bags respectively. With proper care, they will give continuous
service year-after-year.

GASOLINE ENGINE CARE

For care and operation of the gasoline engine, refer to the
engine manufacturer’s operating instructions furnished with the
engine. We recommend draining and refilling the engine
crankcase at least every thirty hours of operation. Check the
engine oil level daily.

The paddle shaft and mixing blades are engaged and
disengaged by tightening and loosening the drive belts with a
spring loaded idler pulley. To engage the clutch, rotate the
lever locates at the front of the mixer counterclockwise. The
spring maintains the correct belt tension. To disengage the
clutch, rotate the lever clockwise against the lever stop. The
engine base is slotted to adjust for belt wear and to bring the
idler pulley into operating range.

CAUTION: Stop the engine before allowing anybody to put
their hands in the mixing drum.

ELECTRIC MOTOR CARE

For lubrication care and operation of the electric motor, refer to
your electric motor instruction booklet furnished with the motor.

Protect the electric motor from dust as much as possible and
keep ventilating openings clean. Do not spray water on the
electric motor.

Refer to the following chart. For recommend plug sizes.

WHEEL BEARINGS

After every 3 months of operation, remove the hub dust cap
and inspect the wheel bearings. Once a year, or when required,
disassemble the wheel hubs remove the old grease and
repack the bearings forcing grease between rollers, cone and
cage with a good grade of high speed wheel bearing grease
(never use grease heavier than 265 A.S.T.M. penetration “No.

2.”) Fill the wheel hub with grease to the inside diameter of the
outer races and also fill the hub grease cap. Reassemble the
hub and mount the wheel. Then tighten the adjusting nut, at
the same time turn the wheel in both directions, until there is a
slight bind to be sure all the bearing surfaces are in contact.
Then back-off the adjusting nut 1/6 to 1/4 turn or to the nearest
locking hole or sufficiently to allow the wheel to rotate freely

position. Install the cotter pin and dust cap, and tighten all
hardware.

PADDLE SHAFT BEARING

The paddle shaft in the Essick Mixer rotates in sealed ball
bearings requiring no additional lubrication.

BEARING BRACKET

Grease the bearing bracket every month.

COUNTERSHAFT

The countershaft rotates on two self-aligned pillow block
bearings. Grease these every 40 hours using grade #1 Lithium
Base grease.

GEAR ALIGNMENT

The countershaft and driven pinion are mounted on a slotted
base. To align gears, loosen pillow block mounting bolts and
move them until the necessary alignment has been made.

GEAR LUBRICATION

The surface of the pinion and the bull gear should be very
lightly greased every 250 hours.

IMPORTANT! AVOID OVER-GREASING.
EXCESS GREASE WILL ACCUMULATE
CONTAMINATES AND CAUSE
PREMATURE WEAR.

IMPORTANT — DRUM HEAD SEAL CARE

On each end of the mixing drum is a drum head containing self
adjusting paddle shaft seals. These seals consist of packing
rings, split glands and spring actuated adjusters. A properly
maintained seal prevents material from working around the
paddle shaft, causing excessive wear. The following is a
suggested procedure of maintenance for protection of the
paddle shaft and bearings:

A. Keep the drum head clean of plaster built up, so the spring
adjusters will be free to work.

B. Replace with one new ring of packing and waterproof grease
when split gland or pressure plate is about to bottom out against
the end of the drum.

New Packing

When the old packing is to be completely replaced, coat shaft
and packing generously with a good grade of waterproof grease
and insert packing rings. Tighten the two spring adjuster nuts
on each end until the spring is compressed to 1¾ inches or the
top of the adjusting nut is even with the top of the drum head.

Also, whenever the paddle shaft is removed, new waterproof
grease should be packed around the ball bearings in the drum
heads before reinstalling the shaft. Fill the cavity completely.

DRUM GRILL

The drum opening is covered by a steel grill that is hinged for
easy cleaning. This grill should be closed at all times when
mixer is in use. Do not remove the grill or grill opening bar.
Keep the grill clean by washing it down daily.

CAUTION: Stop the engine before allowing anybody to put
their hands in the mixing drum.

TOWING — Before towing, check with local and state
laws for proper compliance.

The tow bar and chain must be properly attached to the mixer
and towing vehicle prior to towing. Refer to the following
installation instruction:

Step 1. Insert the Draw Bar into the main frame. Secure, utilizing
the ¾" bolt (grade 5) and nylock nut. Tighten to 100 foot pounds.

Step 2. Install the chain through the hole located between the
frame gusset and frame angle. Loop the chain together and
place under the Draw Bar. Secure with connector link.

Step 3. Extend the chain along the length of the Draw Bar,
remove excess chain (slack) and secure to bottom connector
link. Secure the chain to the towing vehicle, using the
connector link.

NOTE: It is critical that the length of chain be properly adjusted

to prevent the Draw Bar and front mixer stand from
dropping to the ground (contact) in the event the Draw
Bar becomes disconnected from the towing vehicle.

BALL HITCH COUPLER

1. Check vehicle hitch, ball, and coupler for signs of wear or
damage. Replace any parts that are worn or damaged
before towing.

2. Use only the 2" ball diameter as indicated on your coupler.
Use of any other ball diameter will create an extremely
dangerous condition which can result in separation of the
coupler and ball or ball failure.

3. Be sure the coupler is secured to the hitch ball and the
lock lever is down tight and locked.

Recheck tightness again after towing about 50 miles.

4. Check that trailer safety chains are properly connected.

RECOMMENDED MAINTENANCE

1. Smear ball socket and clamp face with chassis grease.
Periodically oil pivot points and solutions surfaces of
coupler with SAE 30 wt. motor oil.

2. When parking or storing your trailer. Keep the coupler off
the ground so dirt will not build up in the ball socket.

replace complete coupler.
