7.Check that the collar block is positioned in the head cutout per Figure 6. If collar block is not properly aligned, check press level. If press is level, shim buck, adjust collar block or discharge tube as necessary. 1/8 in. (3 mm) 1/8 in. (3 mm) 1/8 in. (3 mm) CAB240N Figure 6 8.Press the head release button. Heads should open and buck should return to the dressing station. 9.Simultaneously press and release both buck in buttons. As buck travels into cabinet, press red safety bar which is near the operator. Buck travel should stop, press heads should remain open and air should exhaust from the system. Pressure gauge should read 0 psi. 10.Reset air to press. Simultaneously press and release both buck in buttons. Allow buck to travel into cabinet and heads to close. Press other red safety bar. Press heads should open, buck should remain stationary and air should exhaust from the system. Pressure gauge should read 0 psi. To avoid possible serious injury, NEVER use press unless BOTH safety bars and BUCK IN BUTTONS are working properly. W369WARNING 11.Reset air to press. Simultaneously press and release both buck in buttons. Allow buck to travel into cabinet and heads to close. Press emergency stop button. Press heads should open, buck should remain stationary and air should exhaust from the system. Pressure gauge should read 0 psi. Electrical Check-Out Black and red electrical control buttons start and stop all electrical functions. 1.Reset air to press per step 1 in Buck Indexing Mechanical Check-Out. Turn electrical on to press at fused disconnect switch or circuit breaker. 2.Make sure Emergency Stop button is up if applicable. 3.Press black start button. NOTE: Start button will not start blower unless air is reset to press. 4.Check blower for proper rotation. Check airflow direction at press muffler. Air should be exhausting from muffler. If air is sucked in toward muffler, change any two wires in the electrical connection box. 5.Check isolation damper between sleeve heat exchanger and blower. Air cylinder should extend to open damper. 6.Step on left foot pedal. Vacuum should turn on to buck. Press vacuum release button. Vacuum should turn off to buck. 7.Set cycle timer selector switch to on position and set pressing cycle timer for approximately 35 seconds. Turn steam timer selector switch to off position. Send buck into pressing position. Heads should close and remain closed for approximately 35 seconds. 8.When press heads open, the buck should automatically return to the dressing position. 9.Turn steam timer selector switch to the on position. Set steam timer for 5 seconds. Send buck into pressing position. Blower air should blow through arm holes after a 5 second delay and remain on until cycle timer times out. 10.After all checks (steps 1 through 9) are completed, proceed with Steam Injection and Temperature Check-Out. Steam Injection and Temperature Check-Out The following checks ensure that the steam supply to the press is of sufficient temperature. To avoid possible serious injury or death, perform the following BEFORE proceeding to check out: •Shut off AND lock out ALL electrical power to press. •Shut off AND lock out ALL air service to press. W370WARNING Turn electrical power off. 1.Slowly open shut-off valves in both steam supply and return lines. 2.Open needle valve at water gun assembly. 3.Allow press to heat for at least 15 minutes. 4.Check head surface temperature with pyrometer or temperature stick measuring device. Temperature should be 320° to 340°F (160° to 172°C). 5.Inspect all traps for proper operation per manufacturer’s instructions. To avoid possible serious injury, perform the following BEFORE proceeding to step 6: •Make sure ALL motion has stopped. •ALWAYS be careful to AVOID spring loaded components when working inside press. •NEVER index buck while checking temperature. W371WARNING 6.Turn on air supply to press and reset air system. Turn on electric power to press. Press black start button. Blower will start. Allow press to heat for an additional 5 minutes. 7.Turn both timers off. 8.Check temperature of air to yoke bag snorkel. Send buck into pressing position. Remove plug from tube at top of heat exchanger and insert pyrometer to take air temperature reading. Temperature should be 350°F (178°C). IMPORTANT: Failure to perform the required checks and make corrective actions could result in damage to unit and void warranty. Break-In Adjustments As new press is used, working surfaces “seat-in” and friction decreases. This usually results in increased working speed. These conditions are considered normal in a new press and do not indicate a need for constant maintenance. This initial “break-in” period will vary with usage, but generally occurs during the first week of operation. At this time the following items should be inspected and adjusted if necessary. 1.Recheck the level of press. This is especially important if press is located on wooden flooring. To AVOID possible serious i...
