SET UP
TRANSPORTING AND MOUNTING
When you receive your machine, you will need a forklift for transporting. When lifting the
machine, a sling needs to be used.
Position the machine on a firm cement floor, keeping a minimum distance from 2-1/2 feet from
any wall.
ASSEMBLING THE MACHINE
The following parts will be with your machine upon receiving: Handle and stock stop.
Removing the shipping bolt and screw the handle in the hole. There is a white plug that comes
out of the handle, plug this into its receptacle located on the side of the electrical box. There is a
lever in this attachment, move it to the closed position.

ELECTRICAL CONNECTION
Before connecting the machine to the main power, make sure that the installation has a
disconnected box.
The machine is not equipped with an electrical plug, the customer must provide a suitable plug
for the machine. See diagram below for wire connection. (Green/Yellow wire = Ground)
CHOOSING A BLADE
First the pitch of the teeth must be chosen, suitable for the material to be cut, according to these
criteria:
•Parts with a thing and/or variable section such as profiles, pipes, and plates, need fine
toothing, so the number of teeth used simulations cut.
•Parts with solids sections need wide spread toothing penetration.
•Material made of soft plastic, light alloys and mild bronze also require coarse toothing.
•Attached to the on/off switch on the machine you will find a blade pitch calculator (part
number 71756) with instructions on how to use.
OPERATION
Use recommendations:
•This machine has been designed to cut metal building materials with different shapes,
profiles used in workshops and mechanical structural work.
•Only one operator is needed to use the machine.
•Before starting each cutting operation, ensure that the part is firmly gripped in the vice
and that the end is suitably supported.
•Do not use cutting blades of a different size from those states in the cutting capacity
section.
•If the cutting blade gets stuck in the work piece, release the blade ON button
immediately, switch off the machine and open the vise slowly. Remove the part and make
sure that the cutting blade and/or teeth are not damaged or broken.
•Before carrying out any repairs on the machine, consult the distributor or DAKE.

STARTING THE SAW
•Mix the coolant that comes with the machine at a 10:1 ratio. Add about a half-gallon of
mixed coolant in the machine bed.
•Place material to be cut in the vice (1) and clamp the material in place by turning the
hand wheel (2) clockwise.
•Turn the power switch clockwise to the on position.
•Be sure that the blade is rotating in the correct direction indicated (the blade will rotate
clockwise, be sure the blade is on correctly, also see “changing the blade”) and check to
make sure the coolant is on.
•When the machine is now ready to cut the material. Keep in mind that the cutting speed
and the type of blade, combined with a suitable descent of the head are important for
cutting quality and machine performance.
•When starting to cut with a new blade, be sure to take out the back lash (see “changing
the blade”) on the blade in order to safeguard the blade life and efficiency. The first two or
three cuts must be made while exerting a slight pressure on the part, so that the time
taken to cut is about double the normal time.
•Grip the handle and press the button, slowly move the head in the down position and
begin to cut the material. When you are done cutting the material, release the blade and
move the head in the up position.

CHANGING THE BLADE
Refer to the pictures below for part identifications.
WARNING! Before changing the blade, electrical supply must be LOCKED OUT!
Always use gloves while handling loose blades.
1. Move the head of the saw into its upright position.
2. Using a 5mm hex wrench to remove the safety guard bolt and move the safety guard
back out of the way.
3. Using a 10mm hex wrench, turn the blade bolt clockwise to loosen. When loosened
completely remove the blade bolt and flange that holds the blade on.
a. This is a left-hand threaded bolt, to loosen clockwise turning is required.
4. Take off the old blade.

11 REV012019
5. Clean both sides of the flange that are on either side of the blade and return the inside
flange to its place.
6. Clean all surfaces of the new blade before putting the new blade on.
a. Make sure the teeth are in the downward position, and blade turns clockwise.
b. Line up the holes of the blade with the flange pinholes of the first flange half.
7. Making sure the flange pins are lined up with the pinholes through the blade put the
second half of the flange back on to hold the blade in place.
8. Start to thread the blade bolt back on.
9. While tightening the blade bolt (counter-clockwise to tighten), pull the blade up in reverse
direction and hold it in place as tightening the bolt until it is secure.
a. This is important to remove the back lash.
10. Return safety guard back in position and secure it by screwing the safety guard bolt back
in to place.

spring.
WEEKLY MAINTENANCE
•Sharpen blade.
•Clean blade housing.
•Make sure the gearbox is full of oil.
•Check power chord for any damage.
•Clean and grease the screw and sliding guide vice.
MONTHLY MAINTENANCE
•Check tightness of the screws on the motor, pump, jaws, and safety guard.

SIX MONTH MAINTENANCE
•Change gear box oil.
•Flush coolant tank. This can be done by removing the tank cover on the back of the tank.
And remove the filter screen on the deck of the saw.
•Check all electrical components and connections in the electrical box. Saw vibration may
have loosened items wires or connections.

CHANGING THE GEAR BOX OIL
80/90 Synthetic Gear Oil, we recommend MOBIL SHC635.
Refer to pictures below for further help.
1. Disconnect machine from its power supply.
2. Remove the handle and the plug coming out of the handle that goes to the electrical
box.
3. Use a bucket to collect the old oil; unscrew sight level gauge drain the oil into the
bucket.
4. Once all oil is drained screw the bolt back in.
5. Using the hole where the handle was connected pour in oil until it is visible half way up
the sight level gauge.
6. Screw the handle back on and reconnect the plug.
7. Follow local rules and regulations to dispose of oil properly.
