2 General points

2.1 Safety information

When using battery-powered tools, you must observe basic safety precautions, including the following, to avoid the risk of
fire, battery leaks and injury to persons.

Please read these operating instructions, and in particular the safety instructions carefully before using
the Discman!

Do not operate the device near flammable materials.

Do not touch rotating parts during operation!

Always wear suitable work clothes when operating the device:

close-fitting upper clothing
protective gloves made from suitable material
protective goggles
dust protection for the nose and mouth
wear a hair net if appropriate

Make sure the room is well ventilated.

Protect the device and charger against moisture and rain!

Keep the device and charger in a place that is inaccessible to children!

The device may be operated only with all safeguards and covers attached.

Remove the battery from the device

if it is not in use.
before maintenance work.
when replacing accessories such as the grinding disc.

Keep the device clean and check the charger cable regularly for signs of damage.

If the device is damaged, have it repaired by an approved customer service point only!

Replace damaged grinding discs immediately!

The device must only be used with original MBAS spare parts/consumables. Any use of foreign material shall be at
the risk of the operator and will invalidate the warranty for the device.

The device corresponds to operating mode S 2 and has a operating ratio of 60% 30 min. In other words, after 18 minutes
of grinding, you must switch off the device for 12 minutes.

If the battery is used under extreme conditions (e.g. heat) battery fluid can escape. If this battery fluid comes into contact
with parts of the body, immediately wash it off with plenty of water and consult a doctor.

Follow national regulations for disposing of used batteries!

2.2 Intended use

The device must only be used for grinding the side and base edges of skis or snowboards.

Failure to follow these instructions releases MBAS from any and all liability for damage incurred.

4 Working with the Discman

4.1 Before commissioning

Before you start working remove the locking bolt and the Allen key from the device.

4.1.1

Charging the battery

Charge the battery before you use the edge grinder for the first time; the battery will not reach full power
until it has been recharged multip le times.

Switching off the Discman.
To remove, press the lock and pull out the battery.
Insert the battery into the charger.
Plug in the charger and insert the terminals on the battery in line with

the labels on the charger.
The control lamp [2] shows green when the battery is slotted into the

charger.
While the battery is charging, the control lamp [1] additionally

2

1

flashes red.

Control lamp [2] shows green, and control lamp [1] shows red when

the battery is fully charged (approx. 1 hour).
After charging the battery, unplug the charger.
If you want to charge multiple batteries, you must leave a 15 minute

break between charging sessions.

4.2 Grinding angle setting

1

0 = 90°

To set the grinding angle, release screw [1].
Turn the angle adjuster [2] manually to the desired position.

Turning by one number is equivalent to changing the angle by one
degree. The angle adjuster latches every 0.5 degrees.

Hand-tighten the screw [1] with an Allen key.

2

3.5 = 86.5°

4.4 Grinding disc feed

Turning the knurled nut in PLUS direction [1] moves the
grinding disc towards the steel edge to be ground.

Fit and tighten the parts in this order.

4.5 Replacing a grinding disc

1) With the device switched on, turn the knurled nut to the stop in
MINUS direction.

2) Remove the battery.

3) Remove the angle adjuster and screw.

5) Insert the Allen key through the hole in the angle adjuster into the
clamping screw.

6) Turn the grinding disc until the positioning bolt latches into place.

7) Release the grinding disc clamping screws and remove.

8) Remove the grinding disc and support card and clean the guide
sleeve with a brush.

Do not use compressed air!

10) Remove the positioning bolt.

11) Adjusting the grinding angle (see chapt. 4.2 Grinding angle setting,

page 28).

Only hand-tighten the screw with the Allen key!

4.6 Changing the slide blocks

1) Push out the slide blocks on the left and right with a screwdriver.

2) Push in the new slide blocks until they are flush with the housing.

Whenever you change an abrasive disc, you should also replace the sliding bocks to guarantee grinding of
precise edge angles.

4.7.3

Removing the base edge tuning attachment

1

The deviation of the angle setting can be up to 0.5°.

Check the grinding angle.

Check the grinding results on disused skis or snowboards.
We accept no responsibility for operator error during
grinding!

When grinding the base edge, clamp the ski tightly and make sure that
the Discman can slide freely (ski tightener, ski brake).

1) When removing the base edge tuning attachment, only release the
screws (the spring clip remains on the Discman).

We recommend testing the Discman on disused skis or snowboards.
Above all, after fitting the base edge tuning attachment, you should test the Discman on disused skis or
snowboards.

Grinding direction

Lift off

before start of radius

Please read these operating instructions, and in particular chapt. 2.1 Safety information, page 25 carefully
before using the Discman!
Before grinding, check the sliding blocks for wear and tight seating; replace if needed!
If the grinding disc is applied too heavily there is a risk of excessive heat development!
Always grind side edges before waxing to avoid wax clogging the grinding disc!
Before grinding use a side plane to remove protruding materials from the side edges!

Lower

before start of radius

Discman 2 / 18 V

Before lowering the edge tuning device onto a piece of winter sports
equipment, make sure that the grinding disc does not protrude
beyond the slide blocks to avoid the Discman grinding the steel
edge in an uncontrolled manner when switched on.

Lower the Discman onto the ski or snowboard with the slide blocks
and angle adjuster and push against the ski or snowboard with slight
pressure.

Switch on the edge tuning device and turn the knurled nut counter­clockwise until you see sparks appear.

Switch off the Discman, lift off the ski and check the grinding angle
again.

Again lower the edge tuner onto the ski or snowboard with the slide
blocks and angle adjuster and push against the ski or snowboard
with slight pressure.

After switching on the Discman move the device manually from one
end of the ski or snowboard to the other.

During grinding, you can turn the knurled nut to move in the grinding
stone in case of insufficient material removal, or move out the
grinding stone in case of excessive material removal.

In working position the Discman is in stable state of balance; due to
this ergonomic handling, no force is required to move the edge
tuner; instead apply slight contact pressure and push or pull gently.

36

Discman 2 / 18 V

When tuning the base edge, place your hand on the base edge
tuning attachment as shown to ensure that the base edged is
ground evenly.

The slower the feed speed, the finer the surface!

Make sure that the Discman does not tilt when tuning the
base edge!

After each ski or snowboard change, you must switch off the edge tuner and turn back the grinding disc
with the knurled nut (in direction) so that the Discman does not grind the steel edge in an un­controlled way when switched on.

For consistently good tuning quality, always remove the swarf that occurs after base edge grinding!
