1.1. ELECTRICAL SAFETY
! WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following:
You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and any other
connectors for wear or damage. You must ensure that the risk of electric shock is minimised by the installation of appropriate safety devices.
A Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that a Residual Current
Device (RCD) is used. It is particularly important to use an RCD with portable products that are plugged into a supply which is not protected
by an RCCB. If in any doubt consult a qualified electrician. You may obtain a Residual Current Device by contacting your Sealey dealer.
You must also read and understand the following instructions concerning electrical safety.
1.1.1. The Electricity at Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by a qualified
electrician, using a Portable Appliance Tester (PAT), at least once a year.
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances
and the safety of the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply. See 1.1.1. and 1.1.2.
and use a Portable Appliance Tester.
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply cables and plugs for wear or damage and check all
connections to ensure that none is loose.
1.1.6. Important: Ensure that the voltage marked on the appliance matches the power supply
to be used and that the plug is fitted with the correct fuse - see fuse rating at right.
1.1.7. DO NOT pull or carry the appliance by the power cable.
1.1.8. DO NOT pull the plug from the socket by the cable.
1.1.9. DO NOT use worn or damaged cables, plugs or connectors. Immediately have any faulty
item repaired or replaced by a qualified electrician. When a BS 1363/A UK 3 pin plug is
damaged, cut the cable just above the plug and dispose of the plug safely.
Fit a new plug according to the following instructions (UK only).
a) Connect the GREEN/YELLOW earth wire to the earth terminal ‘E’.
b) Connect the BROWN live wire to the live terminal ‘L’.
c) Connect the BLUE neutral wire to the neutral terminal ‘N’.
d) After wiring, check that there are no bare wires, that all wires have been correctly connected, that the cable outer insulation
extends beyond the cable restraint and that the restraint is tight.
Double insulated products, which are always marked with this symbol , are fitted with live (brown) and neutral (blue) wires only.
To rewire, connect the wires as indicated above - DO NOT connect either wire to the earth terminal.
1.1.10. Products which require more than 13 amps are supplied without a plug. In this case you must contact a qualified electrician to ensure that a
suitably rated supply is available. We recommend that you discuss the installation of an industrial round pin plug and socket with your electrician.
1.1.11. If an extension reel is used it should be fully unwound before connection. A reel with an RCD fitted is preferred since any appliance
plugged into it will be protected. The cable core section is important and should be at least 1.5mm2, but to be absolutely sure that the
capacity of the reel is suitable for this product and for others which may be used in the other output sockets, we recommend the use of
2.5mm2section cable.

wearing approved safety goggles to protect you from swarf and metal
particles. If using cutting oil or coolant a face mask may be necessary to
avoid breathing any vapour generated. Ensure that all other safety
instructions in chapter 1 are followed carefully.
4.1. Head Adjustment. To move the head up or down or to rotate it from side
to side over the bed you must first loosen the head lock nuts ( See fig.1-2 ).
Move the head up or down using the head handle ( See fig.1-16 ).
Rotate the head over the bed if required and then retighten the nuts.
4.2. Speed Adjustment. The table below shows the speeds obtained using
different belt combinations. Use a speed appropriate to the metal you are
cutting/drilling. Disconnect the machine from the power supply before
changing speeds.
4.2.1 To access the drive belts raise the whole head using the head handle until
the top surface of the pulley cover is level with the top of the black cap on
top of the pillar. Unlock the pulley cover by undoing the two catches on the
right hand side of the cover and raise the cover clear of the main pillar.
4.2.2 Loosen the motor leaf screw ( See fig.2-D ) and push the motor towards
the main pillar of the machine in order to loosen the motor
belt. To loosen the other belt slacken off the two bolts holding the central pulley base plate. These are situated either side of the main pillar.
( See fig.2-E )
4.2.3 Move the belts to the desired positions and retension them by pushing the motor away from the main pillar. Tighten the motor leaf
screw first. Then retighten the two bolts holding the central pulley base plate.

4. SET-UP AND OPERATION
fig. 3
fig. 2
4.3 SETTING UP FOR MILLING. ( Disconnect the machine from the power supply while setting up. )
4.3.1 Engaging vertical fine feed. Before commencing milling you should engage the vertical fine feed wheel
( See fig.3-2 ) by fully tightening the engagement knob mounted on the outside of the drill feed hub.
( See fig.3-1 ) ( This will at the same time disable the rapid drill feed. ) Set the depth stop to its maximum
so that it does not interfere with downward movement when setting the height of the milling tool.
4.3.2 Mounting the Cutting Tool. If the drill chuck and arbor are currently mounted, remove them by
loosening the arbor bolt by two turns and giving it a tap with a rubber mallet. The arbor bolt appears at
the top of the spindle shaft and can be accessed by raising the pulley cover ( See fig.2-A ). Ensure that
the drill chuck and arbor are supported as they are removed.
4.3.3 Wear protective gloves at all times especially when handling the cutter. Bolt the cutting tool to the
milling arbor as shown in fig.4 using the hex bolt and washer supplied. Tighten with an 8mm hex key.
Introduce the cutter assembly into the spindle sleeve and hold it in place whilst the arbor bolt is tightened
by hand. Hold the spindle pulley stationary with one hand and tighten the arbor bolt with a spanner. Do not
overtighten.
4.3.4 Attaching the workpiece. The main bed of the machine has 4 inverted ‘T’ slots in it for fixing the
workpiece or any vice/clamping arrangement used to hold the workpiece. The dimensions of the slots are
shown in fig.5 in order to choose appropriate fixings. A 52 piece clamping kit is available as an optional
extra. Part No. SM25/52T.
4.3.5 Setting and locking the cutter height. Once the workpiece is in place the cutter can be lowered to the
required cutting height using the vertical fine feed hand wheel. The height setting must then be locked
using the feed lock handle situated next to the depth gauge ( See fig.3-3 ).
SM25.V3 - 1 - 27/03/07

4.3.6 Locking table travel. To eliminate the possibility of
inadvertantly moving one feed whilst operating the
other you should lock the table feed not being used.
To lock the longitudinal table tighten the two leaf
screws on the front of the table ( See fig.6-12 ). To
lock the cross feed table tighten the two thumb
screws on the right hand side of the cross feed
table ( See fig.6-10 and fig.7 ).
4.3.7 Longitudinal feed stops. In order to control the
length of cut there are two adjustable stops situated
on the front of the longitudinal table. ( See fig.6-9 ).
These stops should be adjusted in relation to the
central fixed stop. ( See fig.6-17 ). Loosen the
adjustable stops with the 5mm hex key provided.
Slide the stop to the required position and retighten.
4.3.8 Calibrated feed. Each feed wheel has an
adjustable calibration ring.
4.3.9 The calibration rings for the cross feed and
longitudinal feed are marked in increments of
0.05mm. One 360Orotation of each wheel advances
the bed through a distance of 2.5mm. Each ring has
a thumb screw which allows it to be reset to zero or
any mark required for a specific cut.
4.3.10 The vertical fine feed has a calibration ring marked
in increments of 0.05mm. One 360Orotation of this
wheel will raise or lower the cutter through a
distance of 2.5mm. Move the calibration ring for the purposes of a specific cut using the thumbscrew provided.
4.3.11 Avoid subjecting drills and cutting tools to excessive strain. Do not apply undue force on the handle in order to cut workpiece. Maintain
a controlled cutting speed through the workpiece.
4.3.12 Adjustable Guard. After the workpiece has been fixed in place on the bed, but before switching on, swing the clear plastic guard
( See fig.6-18 ) round so that it is between your line of sight and the workpiece. Adjust the height of the guard using the two black
knurled knobs on the left hand side of the guard.
4.3.13 Forward/reverse switch. Set the direction of spindle rotation before operating the main on/off switch. The forward/reverse switch is
situated on the left hand side of the main on/off switch mounting box ( See fig.1-6 ). The switch has 3 positions. The central position
marked ‘0’ is ‘OFF’. By turning the switch to the ‘R’ position the spindle shaft will run anticlockwise. By turning the switch to the ‘F’
position the spindle shaft will run clockwise. If the switch is returned to the central OFF position whilst the motor is running the main
ON/OFF switch automatically cuts off the power. Allow the machine to come to a complete standstill before changing the direction of
rotation.
4.3.14 Main ON/OFF switch with emergency shut off. The main ON/OFF switch arrangement is situated on the left hand side of the head.
( See fig.1-15 ). The switch consists of the conventional green ON button and adjacent red OFF button beneath a latching, yellow, outer
cover which carries a large, red emergency shut off button. To access the start button when the outer cover is latched push the
emergency button upwards in the direction of the arrow to release the cover. Hinge the cover upwards and operate the green start
button. To switch the machine off, lift the cover and press the stop button. Alternatively, hit the emergency button which will automatically
lock the outer cover and operate the OFF button beneath it.
4.4 SETTING UP FOR DRILLING. ( Disconnect the machine from the power supply while setting up.)
4.4.1 Vertical feed lock. Before drilling, ensure that the vertical feed is not locked. The feed lock lever should be loose.( See fig.1-8 )
4.4.2 Engaging rapid drill feed. The rapid drill feed is controlled with the three rods emerging from the hub on the right hand side of the
head. ( See fig.3-1 ) The rapid drill feed will not operate if the vertical fine feed wheel used for milling is still engaged. To make the
rapid drill feed operative loosen the engagement knob mounted on the outside of the drill feed hub. ( See fig.3-1 ) Rotate the hub back
and forth to ensure that the hub springs fully outwards.
4.4.3 Depth stop gauge. The depth stop gauge ( See fig.1-14 ) has a graduated scale allowing the drilling depth to be set. Rotate the
primary nut down to the required depth mark and lock it in place with the secondary nut. Alternatively, wind the drill bit down to the
required depth then rotate the primary nut down to the depth stop on the casting and lock it with the secondary nut.
4.4.4 Mounting the chuck with MT3 arbor. If the milling cutter and arbor are currently mounted, remove them by loosening the arbor bolt
by two turns and giving it a tap with a rubber mallet. The arbor bolt appears at the top of the spindle shaft and can be accessed by
raising the pulley cover ( See fig.2-A ). Ensure that the milling cutter and arbor are supported as they are removed ( Wear protective
gloves.) The drill chuck is a shallow taper fit into the end of the spindle shaft. Insert the chuck arbor into the bottom of the spindle
shaft and retain it with the arbor bolt. Do not over tighten.
4.4.5 Mounting a chuck or drill with an MT2 taper. The spindle shaft has an MT3 internal taper into which both the milling cutter and
the drilling chuck can be directly inserted. The arbors are held in place with the long arbour bolt which is accessible when the top
cover is raised (See Fig.2A). When a smaller MT2 taper is required a conversion arbor can be fitted which is MT3 externally but MT2
internally. When this sleeve is fitted the long arbor bolt cannot be used and should be removed. The arbor will be held in place by the
taper. Insert an appropriate chuck or taper drill. Bring the tip of the drill or chuck to bear on a piece of wood placed onto the table and
exert firm but not excessive downward pressure on the drill to retain it in the taper. To remove the MT2 conversion arbor, wind
the rack sleeve down until the slot in the side of it becomes visible. Insert the punch key into the slot and slide it over the top of the
conversion sleeve. A light blow with a mallet should then dislodge the sleeve. Wear protective gloves and support the sleeve as it
becomes loose.
4.4.6 Attaching the workpiece. The main bed of the machine has 4 inverted ‘T’ slots in it for fixing the workpiece or any vice/clamping
arrangement used to hold the workpiece. The dimensions of the slots are shown in fig.5 in order to choose appropriate fixings. A 52
piece clamping kit is available as an optional extra. Part No. SM25/52T.
4.4.7 Speed and direction of rotation. Set an appropriate speed for the drilling operation as described in Section 4.2. Before switching on
set the forward/reverse switch to the ‘F’ position so that the drill bit is turning clockwise. Refer to Section 4.3.13
4.4.8 Switching on. Refer to Section 4.3.14 for the operation of the main ON/OFF switch.
