injury.

MIXER USE AND CARE

� Do not force the mixer to perform an operation other than its intended use. Mixers do a

better and safer job when used in the manner for which they are designed. Plan your work, and

use the correct mixer for the job.

� Never use a mixer with a malfunctioning switch. Any mixer that cannot be controlled with the

switch is dangerous and must be repaired by an authorized service representative before using.

� Disconnect the power from mixer and place the switch in the locked or off position before

servicing, adjusting, installing accessories or attachments, or storing. Such preventive safety

measures reduce the risk of starting the mixer accidentally.

� Store idle mixers. When mixers are not is use, store them in a dry, secure place out of the

reach of children. Inspect mixers for good working condition prior to storage and before re-use.

� Maintain your mixers. It is recommended that the general condition of any mixer be examined

before it is used. Keep your mixers in good repair by adopting a program of conscientious repair

and maintenance in accordance with the recommended procedures found in this manual. If any

abnormal vibrations or noise occurs, turn the mixer off immediately and have the problem

corrected before further use. Have necessary repairs made by qualified service personnel.

� Keep mixer blades clean. Properly maintained mixing blades are less likely to fail and will

perform the job required. Keep handles dry, clean, and free from oil and grease.

� Cleaning and Lubrication. Use only soap and a damp cloth to clean your mixers. Many

household cleaners are harmful to plastics and other insulation. Never let liquid get inside the

motor compartment.

Page of 11 5

� Use only accessories that are recommended by the manufacturer for your model.

2. To change the V-belts (47, 48), loosen the four Hex Bolts located at the base of the Engine.

Slide the Engine to the left to loosen the V-belts. Then, remove the V-belts as shown in the

following illustration. Replace the old V-belts with new V-belts (types A889 and A950). Then

slide the Engine to the right to tighten the V-belts to the proper tension. Correct tension is

obtained when there is approximately 1/4" deflection of the V-belts at the center span of the

Pulleys (40, 41 and 49, 50). Do not over-tension. Then, retighten the four Hex Bolts located at

the base of the Engine (See Figure F).

3. Thoroughly clean the Mortar Mixer at the end of each day’s operation. The Drum may be

scoured for approximately two minutes, using a gravel and water mixture. Then discharge the

gravel/water mixture and hose down the Drum inside and out.

4. Dried cement mix should be scraped out of the Drum. Do not beat on the Drum with a shovel or

other tools to break up accumulations of dried cement mix, as damage to the Mortar Mixer may

result.

5. Do not pour water over the Engine (34). Refer to the Engine manufacturer’s instruction manual

Page of 11 8

for all inspection, maintenance, and cleaning procedures.

6. Periodically, lubricate all moving parts of the Mortar Mixer.

7. IMPORTANT: Whenever a Hub (7) is disassembled for maintenance the following procedure

MUST be followed: NOTE: A bearing packer (not included) must be used for this procedure.

a. Using a suitable solvent, thoroughly clean the Bearing (7), Oil Seal (10), Castle Nut (12),

Cotter Pin (13), and the rest of the parts of the Hub assembly of all old grease, dirt, metal

shavings, and any other foreign materials. The parts must be cleaned, even if they are

new or appear clean.

b. Allow the parts to dry completely.

c. Make sure your hands are clean and the bearing packer (not included) is also clean.

d. Place fresh grease in the bearing packer.

e. With the grease-filled bearing packer in one hand and the Bearing (11) in the other, press

the Bearing into the grease, forcing the grease inside the slots in the Bearing. Continue

doing this until every slot in the Bearing is completely full of grease.

f. To reassemble, carefully slide the Hubs (7) over each end of the Wheel Shaft (2). Insert the

Bearings (11) and Oil Seals (10) on the ends of the Wheel Shaft. Screw a Castle Nut (12)

tightly on the ends of the Wheel Shaft. Then back the Castle Nuts off slightly so that the

Hubs (7) can just move freely (See Figure G).

g. Place a Wheel (8) on each Hub (7). Secure the Wheels to the Hubs, using four Lug Nuts (9)

per Wheel. NOTE: Make sure to tighten (torque) the Lug Nuts to at least 90 Ft.-Lbs. (See

Figure G).

h. Insert a Cotter Pin (13) through the hole at each end of the Wheel Shaft (2) and spread the

Cotter Pins (See Figure G).
