LOTO Performed
Washer Operation - Visually watch machine while in operation (filled with water); check for water and steam leaks from fittings, drain valves, hoses, and door leaks. Check for air leaks. All OEM guards must be intact and fastened as structurally sound as originally designed. Listen for abnormal sounds and address as necessary. Front plate seal should not leak. See Appendix 1.
Washer Chute (if equipped)-Confirm chute air bag does not leak, look over all hardware, bolts, roll pins etc. The very first hydraulic actuator that will begin to stall if the hydraulic pump begins to fail is the chute: also check for oil leaks. Confirm that the chute lands properly in the cradles and that the wheels are in good condition. Reference Appendix 2 for Chute Cradle Assembly. The muffler on the air bag chute quick exhaust valve will reduce the air bag performance. Inspect monthly, replace annuall
Extract Operation - Watch machine in extract; look over extract vibration switch to confirm individual machine ideal settings. On the original wobble stick and steel bracket there should be a baseline clearance of 5/8 inch on the right left and bottom with the machine empty in the run position. Extracts that have the proper load weights should not be too aggressive and not too sensitive. Also refer to the adjustments on the rebalance board (Extract Vibration Switch)
Shocks - Check shocks: visually look over bushings, integrity, and physical damage. Shocks should be warm during high speed extract. Check the Temeperature with an IR Temperature Tool. If ALL of the Shocks are not warm, they must be replaced immediately. It is critical that OEM shocks or equivalent are used to replace tired shocks. The tangs that support the shocks are known to elongate over time and may lead to lost motion in the shock absorber and may need to be replaced after extended run times. See Appe
Door Operation - Check door operation (before shutdown). Should move at a reasonable speed, and not slam. Pneumatic Door latches and limit switches should be observed for function. The door seal should not leak and should be pliable also inspect the sight glass seal: replace as necessary. See Appendix 5 for Sight Glass Specification.
Grout bed and anchors - The grout bed on a washer is the critical foundation for the longevity of a washer and unfortunately is not likely to outlast the machine life cycle: replace upon deterioration. Check anchor bolts semi annually for integrity and tightness. It is wise to keep the nuts greased to reduce oxidation so that the anchor can be managed as necessary. Note: Under loading and overloading of washer will have an adverse affect on the foundation and suspension. See Appendix 4 machine foundation.
Dump valve - Confirm that the dump valve seals when the machine is filled with water: The dump valve skirt should be in functional condition. Check the regulator is working and is supplying 5 PSI of back pressure to the dump valve to keep water out of the valve and valve manifold. See Appendix 6 for Dump valve
Suspension - Check suspension springs: there cannot be fractures or signs of contacting the spring tower the spring cap should not be deformed or concave; these should only be replaced with 3/4 inch thick spring caps (new from Braun in 2011) additionally springs should be replaced in pairs. Where the spring stud enters counter weight the hole should be cleaned periodically then filled with grease. There should be a seven inch gap between the bottom of the counter balance weight and the top of the machine ba
The Machine set up - The machine should naturally be tilted back 3 to 5 degrees; its been noted that this keeps a portion of the load on the rear suspension, keeps debris out of the front basket gap, reduces fatigue of the front door glass. Note the Johnson 700 HD Angle locator is an option for about $14.00
E-Stops - Check all emergency stops and ensure all stop machine operation.
Steam Hose - Check for wear points, chafing, soft spots check the anti whip cable. It is a good idea to document the age of the hose to estimate life cycle and torque the fasteners per the manufactures specifications. See Appendix 9 for Steam anti whip restraint. Adjust and/or replace when necessary.
Electrical Cabinets - Check cabinets; they should be clean and have all conductors neatly arranged (like from the factory) and have raceways covers closed. Door latches should be tight at all times.
Washer basket - Do not enter but visually inspect for the basket for cracks and debris in the basket perforations. The front of the basket should be approximately 3/16 in to 3/8 inch from the machine face the bearing locks should be able to maintain this tolerance when tilting forward and backwards.
LOTO - Perform LOTO in accordance with risk assessment.
Motor Cleaning - Clean motor: closely inspect that no linen has been caught in the motor winding vents on both the left and right sides. Remove ALL lint and dirt.
Tilt Cylinder Lubrication - The cylinder shaft bearings need to be greased every month on a two or three shift plant. Print lubrication appendix or refer to your manual for visual clarity. Remove residual grease from machine surfaces. Refer to Appendix 10 for lubrication schedule.
Paint - Touch up areas of rust and paint failure with Braun Circuit Blue Paint.
Drive Belts (matched set) - Check V-Belts for wear, misalignment, damage and tension. Make necessary adjustments per the manual.
Brakes - Check brake pad thickness and mechanical brake components. Check for properly regulated air supply to the brake unit: the air pressure to hold the brake caliper open is 80 PSI and between 20-50 PSI when the brake is applied. Reference section 10.6 in the Braun manual
Air System - Check air system for leaks and check regulator settings. All gages should be marked with setting requirements.
Hydraulics - Check reservoir level, check for leaks, visible signs or signs of stress on hoses. The Hydraulic pressures are set at 1450 PSI for the door, 1650 PSI for the tilt and 2500 PSI for the Chute. Kendall Four Seasons AW 32 and Sunoco SAE 10W ISO32 have both been specified by Braun. Refer to Appendix 11 for Hydraulics Specification.
Rear Shaft Seal - The rear shaft seal is critical to the longevity of a machine and expensive to repair if left unattended. There should be no signs of water on the rear deck of the washer. It is recommended to inspect the rear deck with the machine tilted back. In the event that there are signs of the rear seal leaking make plans for repair within 45 days.
Chemical Ports - If your Braun washer has chemical port that is lower than the water level, ensure the proper hose bib fitting, hose clamps, and a reinforced hose is used. The reinforced hose must be rated for chemical usage. Check the tightness of the fittings and the condition of the hose. Replace the hose as necessary. Use your Washing Systems Inc Laundry Resource Manager as a resource for these fittings.
Clean Washer - Clean Entire machine of Linen, dirt, debris etc. Power wash the entire bottom of machine
Cleanup - Clean up all tools, parts, and debris from the work area.
