Electrical Equipment:
According to European Standard “CENELEC EN 60 204-1” which simulates modification, publication (IED 204-1)

• The electrical equipment ensures protection against electric shock as result of direct or indirect contact. The active parts of this equipment are housed in a box so that access is limited. The screws can only be removed with a standard screwdriver.
• This equipment is protected against splashes of water and dust.
• This machine has been tested in conformity with EN 60204.

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.
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.

MAINTENANCE

Before performing any maintenance ensure that the machine is LOCKED OUT and unplugged.
Special maintenance operations must be carried out by skilled personnel. However, we advise contacting DAKE. The term special maintenance also covers resetting of protection/safety equipment and devices.

DAILY MAINTENANCE

• Check/fill coolant.
• Check blade wear.
• Check functionality of safety shields.
• Make sure emergency stops are working properly.
• General cleaning and removal of accumulated material.
• Move head to the full upright position when not in use, helps avoid stress on the return 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.
• Check safety shields are not broken.
• Grease the head hinge pin.

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.
• Change the gearbox fluid. Drain all oil out and wipe down box and all gears before refilling. Use 90 weight synthetic gear oil.

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.

should be 24 volts

Auxiliary Relay

| Check voltages to relay terminals, should be 24 volts. If not check for loose wires, if none relay should be replaced
Motor will not work bit the indicator light is on| Socket and/or plug connecting the switch handle to the electrical box| Check the plug connections and the wire connections inside the handle switch
