To reduce the risk of electric shock, motors equippedwith 3-wire grounded plugs must be properly ground-ed. On these motors use only 3-wire grounded plugs,receptacles, and extension cords.

1.9 Connecting Motor to Power Supply

WARNINGImproper use of extension cords can cause over-heating or create serious fire or shock hazards.Never use worn or damaged cords!

Note: Not all countries require the use of a three-wiregrounded plug for this piece of equipment. In thesecountries, motors are equipped with a two-wire plugwhich can be plugged into a standard electrical outlet.

d e1007SD13

1. Check that switch on motor is off before connectingmotor to power source.

2. Make sure power supply matches voltage require-ments listed on motor label. Running a motor at a lowvoltage will cause it to run slow. This will reduceperfomance and may cause motor to overheat.

3. On motors equipped with a three wire grounded pluguse three-wire grounded receptacles (d) when con-necting the motor. If a 3-wire grounded receptacle isnot available, then a grounded adapter must be in-stalled as shown in illustration (e) to ensure a properground connection.

1.11 Operation

Hold head in air or place it on soft surface when startingmotor. This will prevent it from bouncing on hard surfaceswhich could damage bearings. During use, insert thehead quickly into the mix and then pull it out slowly. Rapidremoval is the main cause of poor concrete consolida-tion. For best results submerge head completely and tryto establish a symmetrical pattern for inserting andremoving the head.

Avoid sharp bends in the shaft. This can create hot spots.

When moving around jobsite do not drag head and shafton ground.

Avoid touching forms and rebars when inserting head inmix. This can transmit vibration to other areas of the mixwhich may already be setting.

CAUTION: DO NOT run the motor with the head out ofthe mix for long periods of time. This can cause thebearings to overheat.

For more detailed information on the use, selec-tion and application of WACKER equipment forconcrete consolidation, order Wacker publicationWCW 982 “CONCRETE CONSOLIDATION”.

1. Apply pipe sealant to threads on head (c). Attachhead onto end of flexshaft (left hand thread) andtighten using a wrench.

2. The shaft is attached to motor using a quick discon-nect coupler. The coupler may vary depending on thetype of shaft being used. All new WACKER flexshaftscome equipped with a coupler and do not require anyadditional coupling device. Refer to page 3-4 forshafts equipped with couplers.

If you are using a shaft from another manufacturer, orare attaching an older WACKER shaft, refer to page3-7 to order the correct coupling to use. If a couplermust be installed on the shaft, apply pipe sealant (f)to threads before assembling.

3. Lubricate shaft core. See 1.15 Lubricating Shaft.

4. To attach shaft to motor, pull adapter pin (g) on motorup and slide coupler in place. Rotate coupler until pinfalls into coupler socket.

HMS OPERATION 1A

1A-9

1.12 Periodic Maintenance

Before Operating Inspect air filter and vent holes. Clean or replace dirty or clogged filters.

Inspect electrical cords for wear or damage. Do not use damaged cords.

Every 50 hours Inspect brushes in motor.

Every 100 hours Clean and lubricate core in shaft.

Every 300 hours Change oil in head.

1.14 Motor Housing

Clean motor housing immediately after use, using adamp cloth to remove dust or concrete. Inspect rear airfilter, front screen, and vents on motor housing to makesure they are open. Replace or clean clogged air filterbefore operating motor to prevent overheating.

To clean rear filter: screw out knob and remove cover (d)from motor. Remove filter (e) and wash in warm, soapywater. Allow filter to dry completely before using.

1.13 Motor Brushes

To protect the motor, the brushes are designed to auto-matically shut off the motor if they become too short. If themotor stops during operation, the brushes may need to bereplaced. To avoid having the brushes shut down themotor unexpectedly, inspect brushes every 50 hours andreplace them when necessary. Always replace bothbrushes at the same time.

To inspect or replace brushes:

1. Remove brush caps (a) from both sides of motor.

2. Pull brushes (b) out and measure length. Install newbrushes if length (c) is less than 3/8" (10 mm) long. Ifbrushes are still long enough, place them back inmotor. Make sure they are installed in the samepositions they were removed, to avoid arcing.

3. Break in new brushes by running motor for about 5minutes with no shaft attached.

1.15 Lubricating Shaft

Remove wire core (f) from shaft casing and wipe with aclean cloth.

Apply a liberal amount of flex-shaft grease to the entirelength of the core by hand (g). Insert core into casing androtate it. Repeat this procedure several times.

CAUTION: DO NOT try to force the casing full of grease.A tightly packed casing will put a heavy load on the motorand could cause it to overheat.

CAUTION: DO NOT clean casing or core with solvents.Excess solvent on casing or core may cause grease tobreak down, resulting in damage to shaft.

1007SD15

1007SD14

1.16 Lubricating Head

The bearings in the head are lubricated with oil. Toextend bearing life, change oil in head every 300 hoursof operation.

To change oil:Place head in a vise and remove tip from casing. Ifnecessary, add a couple of small spot welds (h) on tip toprovide a better grip for wrench. Drain old oil from casingand add correct quantity of new oil. Refer to section 1.3Technical Data. Apply pipe sealant to threads on tip andattach it tightly on casing.

Note: In the interests of environmental protection, placea plastic sheet and a container under the machine tocollect any liquid which drains off. Dispose of this liquidin accordance with environmental protection legislation.

Use only SAE 80W140 synthetic oil or equivalent.

CAUTION: DO NOT overfill. Too much oil in the head willoverload the motor.
