INSTALLING A 3 JAW CHUCK
(UK Market only)
A three (3) jaw chuck (part HTA 153) can be fitted into the drive
spindle of S28MAG enabling the machine to take standard parallel
shank twist drills up to Ø13mm (Ø1/2in).
WARNING: Ensure that the machine is disconnected from the
mains power supply when installing the 3 jaw chuck.
To fit the chuck:
• Screw the 3 jawed chuck into the threaded bore of the chuck
adaptor.
(Fig. 10)
• Align the two (2) ‘flats’ machined on the chuck adaptor with the
grub screws in the spindle.
(Fig. 11)
• Insert the chuck adaptor into the bore of the spindle.
• Start to tighten one of the grub screws and at the same time
slightly rotate the adaptor backwards and forwards until the
grub screw is fully tightened. This will ensure that the grub
screw is located squarely onto the flat, preventing the chuck
adaptor from becoming loose.
• Tighten the remaining grub screw.
TO INSTALL AND REMOVE A DRILL BIT
Hold the new drill bit with your thumb and index finger, then
insert it into the chuck. Twist the chuck to tighten the drill bit into
place. If your chuck has a key, insert the key and turn it tighten the
drill bit in place, then turn the opposite direction to slide the drill
bit out.
SETTING UP
(PRIOR TO COMMENCING CUTTING OPERATIONS)
WARNING:
Operators should read the section on intended and
prohibited uses of these machines. Only trained and experienced
operatives should use these machines.
Magnetic Drilling machines should only be used for hole boring/
drilling whilst attached to the workpiece by the electromagnetic
base.
WARNING:
MagDrills must only be used if the electromagnet
is in full working order and exerts sufficient grip on a correctly
prepared workpiece.
Extra vigilance should be exercised if the machine is to be used on
a surface which is inclined from the horizontal.
COOLANT / LUBRICANT DELIVERY
Note:
It is recommended that a Soluble Oil is used as other
coolants/lubricants may have a high viscosity and may not flow
easily to the cutter.
