handles (10,11). A zero position of the slide track is set by

using a dimension on the handles scale. One division on

the scale corresponds with 0,02mm on the table track. If the

axes of the slide track (X,Y) are not in use, it is

recommended to clip them with clutching lever (22).

Turning the milling head (pict. 1, 2, 11-13)

To mill beveled edges or V-grooves, the milling head can be

turned to the left or right about 45°. Warning: before you

start adjusting, make sure that the machine s fixed to the

table properly!

Turn the machine off. Hold the milling head (1) by hand to

prevent it from tilting. Loose the fastening nut (13) with flat

wrench (SW36). Unblock the neutral fixing device (23) by

pulling it out. Set the desirable angle on the angle scale

(24). Tighten up the fastening nut (13) again.

Lead calibration for mitre cuts (pict. 14)

Distance between slide surfaces of cross and longitudinal

slides and milling head can change when using extensively.

To ensure perfect function and movement, the lead for mitre

cuts should be calibrated circa once a year. Loose up a

jam-nuts (25). Adjust the calibration bolts (26) so there is an

even pressure made on the lead for mitre cuts on each

calibration bolt. Hold the calibration bolt (26) with alien

wrench (3mm) in position and tighten up the jam-nut back

again. Tip: Tighten up the calibration bolts evenly, start

always from outside on both sides, to achieve unified

adjustment.

Processing

Drilling and deep milling

Insert a chuck and a tool as described and secure it with a

pulling rod. Tighten up the chuck with chuck key. Set right

revolutions (see paragraph “Revolutions setting”). Fix a

workpiece firmly using machine vice or by using clamping

clips. Move the cross-table (2) into desirable position

(direction X a Y). Adjust a depth stop (see “Normal feed of

the milling head”) and make sure that a workpiece will not

come into contact with a tool. Remove objects you are not

using away from a work place. Turn the machine on and set

right spindle revolutions by revolution selection switch (6).

Drill or mill now. Warning: when drilling large holes, drill

ahead with small drill first. Take the drill out of a workpiece

regularly to get the chips out of the hole. You will get a

drilling or milling depth by adjusting a depth stop (12). After

you are done with your work put the milling head back to

the upper position and turn the machine off. Clean up the

machine and the chucking device and grease them up

possibly.

Counter boring and centralizing drilling

Please take into account that counter boring is done with

low cutting speed and small feed, while centralizing drilling

with high cutting speed and small feed.

Face milling

Fix a chuck and a tool and secure it by pulling rod (19).

Tighten up a chuck with a chuck key. Set the right

revolution range. Warning: Do not change the revolution

ranges (1 and 2) while the spindle is spinning! Fix a

workpiece firmly using machine vice or by using clamping

clips. Move the cross-table (2) into desirable position

(direction X and Y). Adjust a depth stop (see “Normal feed

of the milling head”) and make sure that a workpiece will not

come into contact with a tool. Remove objects you are not

using away from a work place. Turn the machine on and set

right spindle revolutions by revolution selection switch (6).

Mill now. Adjust the cross-table by using manual handles in

a direction X and Y. After you are done with your work put the

milling head back to the upper position and turn the machine

off. Clean up the machine and the chucking device and grease

them up possibly.

After using the machine, working table must be cleaned and

greased again.

Checking, maintenance and keeping

Plug the power cord out of the socket prior to maintaining! Carry

out the machine maintenance regularly (depending on how

often you use it). Document all maintenance jobs.

Keep a taper shank and the mill clean. If not in use store it in a

box. Check the whole function of electric circuit (switches,

sockets, contacts, etc.). To prevent major damage and injuries,

please contact our customer service when dealing with

malfunctions that don’t belong to regular maintenance. You will

find the customer service address in the warranty card. Check

the mobility of the milling head and make sure it will not get

loose.

Check the overshoots at the spindle. Check if all bolt

connections are tightened up.

Lubrication

To get good working results and to protect the machine against

rust, it must be lubricated regularly. Spread out the lubricant

evenly by brush or non-felted cloth.

Places to be lubricated and lubricants:

All metal machine parts: lubricating oil

Toothed rod on a post: lubricating oil

Machine table: lubricating oil

Fine feed mechanism: lubricating oil

Sliding spindle of the longitudinal slides: lubricating oil

Sliding spindle of the cross slides: lubricating oil

Prismatic lead of the milling head: lubricating grease

Turning bearing of the milling head: lubricating grease

Prismatic lead of the cross slides: lubricating grease

Prismatic lead of the longitudinal slides: lubricating grease

Replacement of a power cord

In case of damage power cord, it must be replaced by

manufacturer or by customer service or other qualified person,

to prevent danger.

Cleaning

Pull the power cord out of the socket before every cleaning.

Keep the safety devices, ventilation holes and motor guard dust

and dirt free if possible. Wipe the machine with a clean piece of

cloth or blow it with low pressure pressurized air. We

recommend cleaning the machine after every use immediately.

Clean the machine regularly with dump cloth and soap water.

Do not use chemical detergents and dissolvent that could

damage plastic parts of the machine. Keep the machine out of

the water.

Maintenance

There are no other parts inside the machine that require

maintenance.
