LIFT TRUCK REQUIREMENTS CAPACITY Capacity shown on the nameplate is for the attachment only. The combined truck and attachment capacity is provided by the lift truck manufacturer.

2 LIFT TRUCK REQUIREMENTS CAPACITY Capacity shown on the nameplate is for the attachment only. The combined truck and attachment capacity is provided by the lift truck manufacturer. HYDRAULICS REQUIREMENTS Recommended Truck Pressure: 2000 to 2500 PSI (138 to 172 bar) Hydraulic fluid: petroleum based hydraulic fluid only Hydraulic supply group: includes hoses and take-up - one set for each function Auxiliary valve: 2 Function (Fork Positioning & Side-Shift) = a double auxiliary valve Oil Volume Settings: 6-10 GPM NOTE: EXCESSIVE VOLUME CAN CAUSE PREMATURE WEAR OF ATTACHMENT COMPONENTS GENERAL INSTALLATION PROCEDURES 1. Make sure that the attachment's centering lug is completely seated in truck carriage center notch. 2. Make sure that the lower retainers are sercurely positioned up against the lower ITA bar. LOWER RETAINER Grip both bolts and Squeeze towards center for installation or removal of lower retainer. 3. Attach fork positioning jumper hoses to the fittings as shown. Route hoses so there is enough slack for the frame to side shift. 4. For side shifting attachments install jumper hoses to side-shift cylinder. 5. Standing clear of the attachment, cycle the forks in and out several times to distribute the hydraulic oil, since partially filled hydraulics lines can cause erratic moment. 1

3 MOUNTING OPTIONS The Single Double can be set up for class II or class III mounting. The class II uses 2 shims and related hardware that are not used on the class III. See the illustration below for proper installation. THE FOLLOWING ITEMS ARE FOR CLASS II ONLY # QTY PART # DESCRIPTION SHIM WELDMENT 2 3 1C.0516 BOLT PLT'D 3 3 4E.05 LOCK WASHER FLAT BAR (SHIM) TOP HOOK WELDMENT IS FASTENED TO LOWER MOUNTING HOLES TORQUE TO 245 FT LBS (APPLY LOCTITE #242) BRONZE SLIDES STOP BLOCK ADJUSTMENTS Most models have two postions for the stop blocks. The outside position allows the forks to move farther in single mode (example 28" - 32" single range). The inside position provides quicker conversion to double mode (example 28" single range). to reposition the stops remove bolts and lock washers and align the holes in the stops with corresponding holes in the back bar. Torque bolts as shown. OUTSIDE POSITION SHOWN INSIDE POSITION SHOWN BOLTS & LOCK WASHERS TORQUE 125FT-LBS 2

4 GENERAL WEEKLY INSPECTIONS AND MAINTENANCE 1. Check all hydraulic fittings, hoses, cylinders and valves for leakages - repair or replace as required 2. All bolts should be checked and tightened as required. Check adjusting bolt lock nuts on inner for. If locknut is loose or the bolt is not adjusted correctly adjust so there is approximately.125" between forks when the forks when the forks are close. (See picture below) BOLT LOCK NUT.125" BETWEEN FORKS 3. Operate the attachment from fully closed to fully open several times and check the forks for binding or unusual wear. Correct any problems. See troubleshooting section for more information. 4. Side shift the attachment all the way to the left - grease the upper right hand slide bearing. Side shift the attachment all the way to the left -grease the left hand slide bearing. 5. The frame bearings are self lubricating, although the arms can be lightly coated with general purpose grease to prevent rusting. If operating in dirty environments use dry lube in place of grease. 6. Lubricate the inner fork bearings by applying a small amount of grease to upper slide arms. if operating in a dirty environments use dry lube instead of grease. LUBE HERE 7. The inner fork friction screws may need to be adjusted if the forks are moving when driving around corners. IT IS VERY IMPORTANT THAT THESE SCREWS ARE NOT OVER TIGHTENED AS THIS CAN CAUSE ACCELERATED WEAR OF THE BEARING COMPONENTS. If adjustment is needed remove the screws, clean and apply loctite #242. The screw should be tightened so the fork cannot e moved by hand but not tighter. 3

11 Problem: Inner forks do not sequences properly. TROUBLE SHOOTING-1 Solutions: Check the bronze stop blocks for excessive wear. The contact surface on the bronze stop blocks must be flat to operate correctly. This surface can be ground or machined to correct a wear problem. Up to.20 inches can be removed. If there is less than.44" of engagement the blocks should be shimmed. Shims are available from Loron. After shimming check operational clearance. If the block interferes when in the up position a shim will have to be removed..50".06" MAX.44" MIN Check the steel cam bar on the back of the inner forks for excessive wear. If the bar is not smooth and square it should be replaced..125/.100 RAD. MUST BE SMOOTH SMOOTH AND SQUARE 10

12 Problem: Inner forks lock up or chatter. TROUBLE SHOOTING-2 Solution: If using grease in dirty environment the attachment may be contaminated. Steam clean the attachment and use a dry lube such as silicone or graphite. Inner fork friction screws are too tight. See weekly inspection step #. Check arm slides for nicks or gouges. Correct by sanding or filling. The forks have bronze bearings at the top guide hooks. These are the main guide bushings for the forks and can be shimmed to prevent excessive side movement. The bottom slides can also be shimmed. WARNING: The bottom slides should not be too tight or the forks may lock up or chatter. Check proper clearance by lifting the tip of the fork. There should be approximately.06" to.125" of clearance at the bearing area. BRONZE SLIDES NYLON PAD BRONZE BEARING SET SCREW SHIM BOLT NYLON SLIDES SHIM LOCK NUT 11

TROUBLE SHOOTING-3 Problem: Excessive chain slack. Solution: CHAIN ADJUSTMENT INSTRUCTIONS: 1. Remove cover bolts and cover. 2. Open the arms to the approximate position shown in the picture.

13 TROUBLE SHOOTING-3 Problem: Excessive chain slack. Solution: CHAIN ADJUSTMENT INSTRUCTIONS: 1. Remove cover bolts and cover. 2. Open the arms to the approximate position shown in the picture. WARNING: KEEP HANDS CLEAR WHILE OPENING THE ARMS. 3. Remove Chain Guide. 4. Remove lock bolt and nut. 5. Using an open-end wrench, tighten the adjusting nuts to remove chain slack. There should be little or no slack in the chain when adjusted correctly. Do not over tighten. ADJUSTING NUTS LOCK BOLT AND NUT CHAIN GUIDE 12
