2.4 Emissions

The values stated are emission levels. Although there is a correlation between emission and imission level, it

cannot be reliably derived from this whether additional precautions are necessary. Factors influencing the

current immission level existing at the workplace comprise the duration of exposure, the room characteristic,

other source of noise, etc. such as e.g. the number of machines and other adjacent machining operations. In

addition, the permissible immission level may differ from country to country. This information is nevertheless

suitable for providing the machine user with an improved assessment of the hazard and risk.

Any other use than described above is not

permissible. The manufacturer cannot be held liable

for any damage arising from such other use.

So as to use the machine as intended, comply with

the operating, maintenance and repair instructions

specified by Mafell.

2.7 Residual risks

Danger

Even if used in accordance with its

intended purpose and despite

conforming with the safety

instructions, residual risks caused

by the intended use will always

remain.

- Touching the sanding paper or the oscillating plate

when sanding.

- Touching live parts with the housing open and the

mains plug not removed.

- Hearing can be impaired when working for long

periods without ear protectors.

- Emission of harmful wood dusts during longer

operation without extraction.

3Safety instructions

Danger

Always observe the following safety

instructions and the safety

regulations applicable in the

respective country of use!

General instructions:

- Children and adolescents must not operate this

machine. This rule does not apply to young

persons receiving training and being supervised by

an expert.

- Never work without the protection devices

prescribed for the respective operating sequence

and do not make any changes to the machine that

could impair safety.

- When operating the machine outdoors, use of an

earth-leakage circuit-breaker is recommended.

- Damaged cables or plugs must be immediately

replaced. Replacement may only be carried out by

Mafell or an authorised MAFELL service workshop

in order to avoid safety hazards.

- Avoid sharp bends in the cable. Especially when

transporting and storing the machine, do not wind

the cable around the machine.

Instructions on the use of personal protective

equipment:

- Always wear ear protectors during work.

- Always where a dust mark during work.

- The dust arising during work is often hazardous

(e.g. when processing oak or beech wood, rocks,

metal or paint coats containing lead or other

harmful substances) and should not enter the

body. Do not touch or inhale the dust. Use a dust

extraction and in addition wear a dust protection

mask. Remove any deposited dust thoroughly, e.g.

by vacuuming it with a special vacuum cleaner.

Also observe this when replacing the filter bag.

Instructions on operation:

- Do not reach with your hands into the oscillating

range of the sanding paper or its retainer. With

your other hand, support the supplementary

handle or the motor casing.

- Never support the workpiece in your hand or over

your leg. Secure the workpiece against a sturdy

support.

-17-

- Whenever possible, secure the workpiece against

slipping, e.g. with screw clamps.

- Provide for an unobstructed and slip-proof location

with sufficient lighting.

- Only use sanding paper with the dimensions stated

in these operating instructions.

Instructions on service and maintenance:

- Regularly cleaning the machine, especially the

adjusting devices and guides, constitutes an

important safety factor.

- Only original MAFELL spare parts and accessories

may be used. Otherwise the manufacturer will not

accept any warranty claims and cannot be held

liable.

Only connect the machine with the

mains when it is switched off.

4Setting / Adjustment

4.1 Mains connection

Prior to commissioning make sure that the mains

voltage complies with the operating voltage stated on

the machine's rating plate.

4.2 Dust extraction

Connect the machine to a suitable external dust

extractor during all work generating a considerable

amount of dust. The air velocity must be at least 20

m/s (65.6 ft / sec.).

The internal diameter of hose connector is 35 mm ( 1

3/8 in.).

Correct dust extraction can only be guaranteed if an

abrasive grid or punched sanding paper is used. As

the sander is equipped with its own dust extraction, it

is possible to work with the sander's own dust

extraction and the filter bag supplied for short

assignments and in inaccessible areas. Make sure

that the filter bag is replaced on a regular basis (Fig.

5 and 6).

4.3 Replacing abrasives

Danger

Pull the power plug during all

service work.

Attaching abrasives with hook and loop fastening

(Fig. 2)

The hook and loop fastening makes a quick

replacement of the sanding sheets possible.

Remove any dirt and dust from sanding pad 6 or

7 before mounting a new sanding sheet.

When abrasive grids are used, the Velco strip of

the sanding pad can be covered with protective

layer 9 or 10 to prevent excessive wear.

When positioning the protective layer, pay

attention that the drill holes correspond to those

of the sanding pad.

Make sure that the clamping brackets 4 (Fig. 1)

are always locked in position when working.

Loose clamping brackets wear and may

damage the casing of the orbital sander.

Only use original MAFELL abrasives.

Attaching sanding paper without Velcro fastening

(Fig. 3)

Release clamping bracket 4 by simultaneously

lifting the two rounded ends 5 upwards.

Remove the old sanding paper and insert a new

sheet.

When positioning the sanding sheet, pay

attention that the drill holes correspond to those

of the sanding pad.

By exerting pressure on clamping brackets 4

you fasten and clamp the sanding sheet in

position.

Make sure that the release levers on both sides

engage.

4.4 Installation of the delta grinding plate

Installation of the delta grinding plate

(Fig. 4)

Open the clamping bracket 4 by lifting the

rounded edges 5 on both sides and pulling back

the clamping bracket. Then, press the two

brackets against each other from the outside

and remove clamping bracket 4 from the

sanding pad.

-18-

Insert delta sanding plate 7 with its two cams

from the front into sanding pad 6. Attach the

delta sanding plate 7 with screw 11 to sanding

plate 6.

4.5 Additional handle

If necessary, the additional handle 12 can be

removed from the machine with the integrated screw

13 using the enclosed hexagon screw driver.

5Operation

5.1 Initial operation

Personnel entrusted to work with the machine must

be made aware of the operating instructions, calling

particular attention to the chapter "Safety

instructions".

5.2 Switching on and off

Short operation

Switching on: Press switch 1 (Fig.1).

Switching off: Release the switch.

Continuous operation

Switching on: Press switch 1 and locking

button 2 consecutively. Then release the switch

with depressed locking button. The motor runs

without pressure on the switch.

Switching off: Press switch 1 until locking

button 2 pops out. Then release the switch.

5.3 Control electronics

The stroke rate of the orbital sander UVA 115 E can

be steplessly set at adjusting wheel 3 of the control

electronics from 4000 strokes/min to 24000

strokes/min.

With the control electronics, the sanding speed can

be adapted to the respective material. Thus, heat-

sensitive materials such as plastics, paints, varnishes

and glazes are protected against damage by

excessive sanding speeds. In addition, the abrasive

grid lasts longer as it does not get clogged. Thus,

when working with the control electronics when

sanding a wide variety of different materials, you

always obtain a sanding speed that is suitable for the

material.

5.4 Work instructions

The best sanding performance is achieved with slight

pressure.

You can avoid scratching caused by switching on and

off, if you position the running orbital sander on the

workpiece and also remove it with running motor from

the workpiece.

6Service and maintenance

Danger

Pull the power plug during all

service work.

MAFELL machines are designed to be low in

maintenance.

The ball bearings used are greased for life. When the

machine has been in operation for a longer period of

time, we recommend to hand the machine in at an

authorised MAFELL customer service shop for

inspection.

Regularly remove deposited dust from the machine.

In the process, blow out the ventilation openings on

the motor.

6.1 Storage

If the machine is not used for a longer period of time,

it has to be carefully cleaned. Spray bright metal parts

with a rust inhibitor.
