OPERATION MANUAL PB-GL SERIES SAFETY SYMBOLS Fixed to the front of the press brake are safety symbols designed to make sure the machine is safely operated CENTRE WORKPIECE Hearing and eye protection are extremely important as the result of an injury to these parts of the body may cause permanent damage.
OPERATION MANUAL PB-GL SERIES 2.3 LIFTING INSTRUCTIONS On the day that the machine arrives, make sure that a crane with sufficient capacity is available to unload the machine from the vehicle. Ensure access to the chosen site is clear and that doors and ceilings are sufficiently high and wide enough to receive the machine.
3.1 SITE SELECTION AND PREPARATION The METALMASTER Press Brake must be installed on a rigid and stable floor such as a concrete slab 150 - 200mm thick. The press brake will be more stable if it sits on one slab and does not straddle slabs.
OPERATION MANUAL PB-GL SERIES 3.2 MACHINE LEVELING To set your machine up so that it operates to optimum performance, apply the following leveling procedure After your guillotine has been anchored to a concrete slab floor, it then needs to be leveled. The leveling is performed using the screws on each pad.(Fig.
3.5 CHECKING THE POWER SUPPLY METALMASTER machines are supplied wired ready to run. Check the specification plate on the machine to confirm the local voltage is the correct voltage for the machine.
OPERATION MANUAL PB-GL SERIES 3.6 ATTACHING THE ACCESSORIES. q Bolt the support arms onto the feed table. Ensure they are level and square to the table. (Fig.3.3) .3.3 q Unpack and attach both the side guards to the machine making sure they are square with the machine. (Fig3.4) .

OPERATION MANUAL PB-GL SERIES 4.7 LASER SAFETY DEVICE PERIODICAL CHECK The alignment & calibration of the laser system emitter & receiver along with the machines punch tooling shall be checked using the supplied calibration & testing aids. Section 4.5 “Laser guarding setup and Calibration” shall be used for the setup & calibration Refer Page 22 of this manual.
OPERATION MANUAL PB-GL SERIES 4.8 CONTROLS The purpose of this control overview is to provide the novice machine operator with a basic understanding of how the machine is used during operation, and the machine controls and what they do. It also helps the operator to understand if they are discussed later in this manual.
OPERATION MANUAL PB-GL SERIES 5. OPERATION The Model PB-135E will perform many types of operations that are beyond the scope of this manual. Many of these operations can be dangerous or deadly if performed incorrectly. The instructions in this section are written with the understanding that the operator has the necessary knowledge and skills to operate this machine.
PB-GL SERIES 5.2 TESTING THE EMERGENCY STOPS The Metalmaster Press Brake model PB-135B is fitted with two emergency stop buttons. One is on the mobile foot pedal and the other is on the pendant control panel. They should be tested one at a time to ensure they are working correctly.

PB-GL SERIES 5.5 E21 PRESS BRAKE CALIBRATION: X AXIS The Metalmaster Press Brake is calibrated before the machine leaves the factory and should not need to be calibrated. However should the machine at any time need to be calibrated, the following is the procedure.
OPERATION MANUAL PB-GL SERIES 5.5 E21 PRESS BRAKE CALIBRATION: Y AXIS The model PB-135E Press Brake has no hard limit micro switches fitted to the machine. It relies simply on the soft limits. The Soft limit is a Software limit that is set on the controller 1.
OPERATION MANUAL PB-GL SERIES 5.6 REMOVING & REPLACING TOOLS Installing and Removing The Die: To remove the die, loosen the clamp screws (Fig.5.8) and lift the die off the machine. NOTE: Please use safe lifting practices when removing or replacing the die.
OPERATION MANUAL PB-GL SERIES 5.7 ALIGNING THE PUNCH AND DIE When you reinstall the dies after removing them together with the die holders, align them again. To Align the Tools: 1. Start the machine. 2. Set the mode to “INCH”.
OPERATION MANUAL PB-GL SERIES 5.9 BENDING TECHNIQUES There are two basic bending techniques: - AIR BENDING This method is commonly performed because relatively low bending forces are required - COINING This method requires forces approximately three to five times those of air bending. It allows the inside radius to be coined.
Metalmaster advise that shimming the bottom die is quicker and will save the operator time. NOTE: If at any time the wedges need to be adjusted we recommend that this be carried out by a Metalmaster service engineer . 6.3...
OPERATION MANUAL PB-GL SERIES 6. MAINTENANCE 6.1 MAINTAINING HYDRAULIC SYSTEM When dirt, dust, and other foreign matter are deposited in large amounts in the hydraulic cir- cuit, the hydraulic pump may produce abnormal noise and decrease in discharge capacity, and the ram may decrease in bending speed and vibrate.
Page 39
OPERATION MANUAL PB-GL SERIES HYDRAULIC SYSTEM OF THE MACHINE The hydraulic system working principles are displayed in Fig.1. INACTIVE: When the oil pump is running, the oil feeds out, through an oil pipe and into the valve plate and solenoid valve, then returns into the oil tank. At this time the solenoid valve isn’t working, The No.12 valve is closed and the top beam is stationary .

OPERATION MANUAL PB-GL SERIES 6.2 LUBRICATION Before maintaining or cleaning the machine, turn off the circuit breaker, and relieve the residual hydraulic pressure in the machine. Post a sign to inform other workers that the machine is under maintenance Lubrication is very important to maintain bending accuracy and avoid machine troubles. Be sure to appropriately lubricate the machine according to the Lubrication chart below and s also found on the side of the machine.
PB-GL SERIES 6.3 SYSTEM ERROR LIST PB-GL Series machines incorporate internal functional monitoring, this allows easier diagnostics of non mechanical errors that may inhibhit the use of the Pressbrake, These errors are often not seen by the user and generally require an experenced serivce techncian to resolve.
