the confidence you demonstrated to
us by making this purchase.
We tried to supply you with an
efficient and dependable machine.
Prior to starting-up this machine, read
the operating manual carefully. It will
inform you in detail about operation
of the unit and provides valuable
advice for service and maintenance.

Provisions for use

The KS 27 M is designed exlusively
for sweeping floors, e.g.
in production facilities, warehouses,
parking sites, and pedestrian areas,
for collecting both, dry and moist
matter.
Use in excess of these specifications
will be deemed to be improper use;
the manufacturer cannot be held
liable for consequential damage;
proper use also includes that main­tenance work is done as specified by
the manufacturer.

Caution: The machine must not
be used for evacuation of dusts
dangerous to health!

Acceptance
of the machine

As soon as the machine arrives,
please check whether any damage
has occurred in transit. This will be
refunded to you if you have the
damage confirmed immediately by
the Railway Officer or by the
Forwarding Agent, and send the
statement of damage together with
the bill of lading to

First operation

Assembly

For reasons of packaging, handlebar
and side broom arm, to include
broom and Vee belt are not assem­bled. After unpacking the KS 27 M,
first assemble the handlebar and the
side broom next.

A

Attach handlebar

Bolt handlebar to both sides of the

housing, use the wing bolts (A/1)

Note: The handlebar can be mounted
in two positions, as suitable for the
operators’ tallness.
For short people: Install the handlebar
with handle rod bent to downside.
For average and bigger tallness:
Install the handlebar with handle rod
bent to the top end.

B C D

Attach side broom

Unpack side broom arm and

broom;

Plug side broom on broom shaft

and secure with bolt; use 10 mm
spanner size. Do not overtorque
bolt to avoid damage to the broom
hub;

Place the Vee belt in the pulley

over the RH wheel; side broom will
have to rotate CCW when machine
moves forward (top view);

6

Attach size broom arm with plug

(C/1) and safety pin (D/3).
Introduce plug from outside;

Slue side broom down and adjust

broom height, or better said,
broom pressure with knurled-head
bolt (D/1); loosen knurled nut (D/2).
Side broom should not be seated
on the floor with more than 2/3 of
its circumference. Secure with
knurled check-nut;

 Check belt tension, adjust tension

as required (refer to para. ”Side
broom“ on page 21).

Operating the
KS 27 M

All controls are identified by easy-to­understand symbols which will help
you to get familiar with the machine.
The KS 27 M uses two
brooms. The dish-type side broom
feeds the matter swept to the main
broom. The main broom is rotating
against the direction of travel of the
machine and throws the dirt into the
dirt hopper located at the forward
end.
Both brooms are driven by the ma­chine wheels.
A jackwheel will guarantee uniform
ground clearance and perfect swee­ping. The broom housing uses rubber
seals all around to seal it against the
floor surface. At the forward end, the
broom housing is
closed by the dirt hopper, at the rear
end a large rubber lip is assembled.

If any part of the floor shall be omit­ted (smeared floor or transport), just
lift both brooms from the floor by de­pressing the handlebar. Steps and
stairs are easily overcome by the
KS 27 M. The large wheels extend bey­ond the rear end of the machine. This
means that all usual obstacles are
overcome by pulling the machine
”uphill“ or pushing it ”downhill“.
The handlebar is folding to ease
transportation or storage of
the KS 27 M.
For folding, loosen both wingbolts a
few turns, expand the handlebar
structure and fold forward.

adjustment

is used for adjustment of the swee­ping roller ground pressure.
The sweeping roller ground pres­sure should be adjusted as recom­mended by us, or be adapted to
local conditions, until good swee-

ping performance will be achieved.
Adjustment is indicated by the
scale close to the track wheel.

Note: Sweeping roller ground pres­sure, if adjusted to too high a
value, requires higher physical
force to push the machine, and
increases the wear of brooms. Best
sweeping performance will be
achieved at

2.5 m.p.h. = 4 km.p.h., i.e. normal
pedestrian’s speed.

2 Hopper handle

is used to remove the dust hopper.

3 Butterfly nuts for fixing

of handlebar

are used to secure the handlebar.

4 Handwheel to adjust side broom

The broom may touch the floor
with the forward 2/3 of its circum­ference only so that it can feed the
rubbish to the forward end of the
main broom and not sweep it
around only. The preset working
level of the side broom is kept con­stant as soon as the knurled nut
(checknut) is tightened in position.

Emptying the dirt hopper

To lift the dirt hopper, just use the
handle provided.

Insert the dirt hopper

Locate the hopper on the forward
frame as shown, and slue down.
Note: Do not place the dirt hopper
flat on ground to avoid damage to the
rubber lip. Use the four feet for sto­ring the detached hopper.

Replacement of main
broom

The broom roller bears 10 ea. rows of
alterned soft and hard bristles and
consists of two broom halves.
Width: 480 mm (18.9")
Dia.: 250 mm (9.8")
Dia, wear limit: approx. 180 mm (7.1")

10

The broom roller is replaced as
follows:

Slue side broom up
Tilt machine back to rest on the

handlebar

Remove three ea. Phillips screws,
turn broom roller 180°, remove
Phillips screws from second half. Pull
the drive pin out of the broom shaft.
To install, reverse above procedure.

Side broom

The side broom is driven by a Vee
belt from the RH wheel. Slueing down
the side broom will tension the belt,
and driving condition thus will be
established.

Replacement
of side broom

Slue-up side broom arm
Remove clamp screw underneath

side broom (spanner size 10 mm)

Pull out side broom
Plug-on new side broom and

secure. Do not overtorque clamp
screw to avoid squeezing the
bristles hub.
Note: Adjust ground clearance with
handwheel (A/1) so that
broom circumference is going
to touch the floor. Higher load will
cause excessive bristle wear
and more power for moving the
machine.

/3of the

Adjust tension of side
broom Vee belt

To tension the Vee belt, proceed in
the following way:

Slue-up side broom;
Loosen bolts (B/2), should come

out approx. 5 mm (0.2");

Lift roller holder (B/1) from slot in

plastic rib;

Slue roller holder (B/1) out, intro-

duce into next slot, slue back and
tighten;

A B

Slue down side broom, check ten-

sion, readjust as required.
Note: Adjust Vee belt tension just
as far as required to ensure power
transmission. Do not adjust too
high a tension of the Vee belt to
avoid excessive load and wear to
the side broom, and to preclude
poor sweeping performance.

Replacement of side
broom Vee belt

To remove or to re-install a Vee-belt,
proceed in the following way:

Remove side broom
Remove washers, deflector plate

and spacers from broom shaft

(fig. A);
Remove circlip, pull washers and

pulley with Vee belt off shaft (key

should not drop out from the shaft);

12

Fit new Vee belt on pulley and re-

assemble (reverse the above pro­cedure).
Note: After having assembled the
pulley, check for key in place (refer
to sketch right above).

Check:

Move Vee belt to the right, shaft will
have to follow, move Vee belt to the
left, shaft will have to stand still. (view
into side broom arm).

Location of key:

(bottom view, into side broom arm)

Sealing lips

The rubber sealing lips will avoid dust
to be expelled by the broom.
Damaged or worn-out lips will have
to be replaced.

Grease track wheels

For cleaning and greasing the axle
and pinion, remove track wheels as
follows:
Remove hub caps

Insert two screwdrivers into the
slots marked by arrows, and remo­ve the hub cap using the screwdri­ver as a lever, applying force in a
uniform manner (fig. A).

Then remove the circlip from the

wheel axle and remove the track
wheel (fig. C).

Grease axle and pinion
Re-assemble track wheel.

Attach hub cap as shown in fig. B,
check for index marks in place
(arrows).
