Proper operating technique and common sense can help prevent damage to the product and to the attachment, as well as contribute to a safe working environment. The purpose of this Operation Manual is to suggest ways you, as the operator, can learn the techniques and tricks professional operators use every day. Study this manual and familiarize yourself with the attachment. Learn to recognize normal operation and indicators of problems before they cause downtime. Take a few moments to look the attachment over to spot areas that may become a problem later. This manual will show you what to look for as well as proper operating techniques. If you have any questions about procedures in this manual or about the attachment be sure to ask your supervisor or an experienced, trained operator before proceeding. Loron's Soft-Touch clamp is designed to take many of the clamp force decisions away from the lift truck operator so that the correct clamp forces will consistently handle a variety of loads with minimal clamp force to reduce product damage. Conventional clamps include articulating pins located on the outside of the clamp arm to help even out clamp forces front-to-back. Loron's patent pending Soft-Touch design has a series of bladders located between the outer plates and inner contact pads. The bladders create a full-floating pad assembly that greatly improves the distribution of clamp forces throughout the load being clamped. In addition, the positioning of the bladders create a leverage system so the clamp forces will vary, depending where the load is within the clutches of the pads. In other words, clamp forces automatically adjust proportionately to the contact area of the load. Lowest clamp forces are achieved when product is clamped at the leading edge (tip) of the pad, medium clamp forces in the front set of pads and full clamp force when both the front and back pads are engaged with a load. Clamp forces are also reduced when short loads are clamped. If the load is small enough to fit in the front set of pads, clamp product in the front pads so the back of the load is even with the leading edge of the pad. When the load becomes larger, the back pads will become engaged with the load, automatically increasing clamp force. If a single television is being handled, clamp the load at the tip of the clamp. Clamp the load gently, watching for any undesired creasing in the packaging. This is a special handling case. All other loads should be clamped at full speed so the clamp can adjust the force automatically. A clamp force gauge or clamp force gauges are important for initial clamp force setup. In addition, clamp forces should be verified periodically to insure desired clamp forces are maintained. The bladders are pressurized with water or a non-toxic antifreeze, such as used in RV's drinking water system during winter months. At rest, the bladders should be pressurized between 4-6 psi and should be checked on a regular basis. The pressure gauge is easy to view and very accessible. Fluid levels will stabilize, but it is very important that periodic checks are established to maintain fluid levels. One vacuum filling pump will be provided to each location using Loron's Soft-Touch clamp technology. 1 MAJOR APPLIANCE CLAMP PARTS Load Backrest Front Pad Clamp Force Control Valve (Location Varies) Clamp Valve Frame Back Pad Cylinder Guard Arm Weldment 2 Be sure the truck is shut off prior to inspection. DAILY INSPECTION 1. Check Water Pressure gauge, if not in operating range (Green Zone) refill with RV antifreeze. See Loron Bladder Fill Manual NOTE: Use water glycol containing no alcohol. 2. Check level of hydraulic oil in lift truck hydraulic reservoir. 3. Check for presence of hydraulic oil on attachment indicating possible leaks. 4. Visually inspect mounting points to be sure the attachment is securely mounted to the lift truck. 5. Inspect pads for damage. 6. Actuate attachment functions. Report any unusual behavior to your supervisor. Be sure the truck is shut off prior to inspection. WEEKLY SERVICE 1. Check all hydraulic fittings, hoses, cylinders and valve for leakage. Repair or replace them as required. 2. Check hoses for pinch points and signs of wear. Contact supervisor if hoses are badly worn, have cuts, bulges, or are fraying. 3. All bolts should be checked and tightened as necessary. 4. Inspect all weld joints for signs of cracking. LOAD HANDLING TECHNIQUES In the following pages you will find a suggested method for basic load handling. Experienced operators often develop their own techniques as they gain confidence in the equipment and their abilities. The examples show how to handle a load using an Appliance Clamp. In order to pick up a load with the Applance clamp, firmly clamp down on a load and hold for two seconds. 3 PICKING UP PRODUCT - 1 Step 1: 1-1) Stop in front of the load tilt mast vertical Step 2: 2-1) Square the truck to load and open the arms for clearance. 1-2) Align the bottom of the attachment to bottom of the load. 2-2) Align by sideshifting. Step 3: Step 4: 3-1) Drive forward to engage the load. See illustrations below for proper load handling. 4-1) Clamp at full speed and hold for two seconds. XClamped product should be positioned so that the load is even with the leading edge of the pad. Clamp product from front to back instead of back to front. Approved methods of Product handling for different loads. 4 PICKING UP PRODUCT - 2 Step 5: 5-1) Raise load for clearance of stack or floors. (Check for ceiling clearance). Step 6: 6-1) Drive back slowly from other boxes or the stack. Step 7: Step 8: 7-1) Lower the load from stack. 7-2) Tilt the load back for transport. 8-1) Center the load to truck. 5 DEPOSITING PRODUCT - 1 Step 1: Step 2: 1-1) Stop in front of the load tilt mast vertical. 2-1) Square the truck to the stack. Step 3: Step 4: 3-1) Raise load for clearance of stack. (Check for ceiling clearance). 4-1) Drive the truck slowly forward. 4-2) Square the load to the stack and lower the load slowly. 6 DEPOSITING PRODUCT - 2 Step 5: 5-1) Open arms releasing load. 5-2) Watch for clearance to other loads. Step 6: 6-1) Drive back slowly from the stack. 6-2) Lower the attachment. Step 7: Step 8: 7-1) Tilt the mast back. 8-1) Center the attachment to the truck. 7 LOADING / UNLOADING TRAILERS / BOXCARS - 1 Step 1: 1-1) Inspect trailer for damage before unloading or loading. 1-2) Make sure the dock-plate is in place. 1-3) Block up the Trailer wheels. CAUTION: slow over dock-plates Step 2: 2-1) Watch for clearance when entering or exiting with a load. 2-2) Stay centered in the trailer and brake gently. 8 LOADING / UNLOADING TRAILERS / BOXCARS - 2 Step 3: 3-1) Position the arm between the load and trailer wall. 3-2) Use side shift to move the load away from the wall Step 4: 4-1) Clamp at full speed and hold for 2 seconds. 4-2) Back up slowly. 9 SAFETY PRECAUTIONS Please follow the safety precautions below to help prevent personal injury or damage: Prior to operating the lift truck and attachment you must recieve proper training and get certification as an operator. Know the capacity of the lift truck and the attachment. Handle loads weighing at or less than the lowest stated maximum capacity only. Truck and attachment may have different maximum capacities. When leaving truck, lower attachment to floor, shut off truck, place transmission in park (or put in gear for trucks with manual transmissions) and set the hand brake. Transport loads near to the floor with mast tilted back. Obey speed limits. Drive only in designated aisle. Obey all stop and caution signs. Sound horn at blind spots. Back Straight down inclines. Drive straight forward up inclines. If load obstructs view drive truck in reverse. If load is unstable or separating, restack load prior to handling. Always keep arms and legs within the confines of the operator's compartment. Keep others off of and out from under the attachment at all times, whether empty or loaded. Operate the attachment only if it is in good condition and functioning properly. Always keep clear of moving parts while truck is turned on. Avoid pinch points. Use the attachment only as specified in the manual or instructed by your supervisor or trainer. misuse can lead to damage to the load or attachment and may cause personal injury. 10 NOTES 11
