INTRODUCTION This users manual covers portable tower installation and usage on S21M EZ liner systems. The S21M portable tower (see Figure 1) allows technicians to make pulls at sides or at rear of machine. It attaches to a pedestal (see Figure 2) that adjusts forward or rearward along the inner channels of the mainframe. The tower operates from the EZ Liner control switch individually or simultaneously with existing towers and auxiliary rams. DO NOT attempt to operate the S21M portable tower without first reading this entire users manual. Complete safety information is highlighted throughout the manual and is identified with. This safety alert symbol identifies safety information in the manual and operator injury could result if these CAUTION notes are not followed. The pedestal provided with the S21M portable tower can be installed in either the center or rear section of the machine. Once the pedestal is installed by a qualified Chief Automotive Technologies, Inc. service representative, it should not be removed. Transferring a pedestal from one section to another is time consuming and potentially dangerous if not done by a qualified Chief service representative. It is more productive to install pedestals in both the center and rear sections of the machine. Additional pedestals are available from Chief Automotive Technologies, Inc. that can be installed either in the same section or in an adjoining section of the machine. CAUTION: To prevent personal injury and damage to equipment: 1. Installation of the S21M portable tower pedestal components must be done by a qualified Chief Automotive Technologies, Inc. service representative. 2. Always wear safety glasses during usage of S21M portable towers. 3. DO NOT attempt to use S21M portable towers in conjunction with any other repair system. 4. Detach portable towers from S21M EZ Liner system prior to lowering machine. 5. DO NOT use S21M portable tower as a device for moving machine. 6. DO NOT use portable tower chain (3/8-12 with hook) on the front towers of the EZ Liner S21M machine. The front towers require 1/2-12 tower chains with hooks. Figure 1 Figure 2 1
USAGE Many of the usage procedures and safety precautions for S21M front towers also apply to portable towers see Towers, EZ Liner S21M Users Manual. In addition, there are usage procedures and safety precautions that apply specifically to portable towers. These are included in this manual. NOTE: Pulling capacity of S21M portable towers is less than S21M front towers. Portable towers house a 5 ton hydraulic cylinder (8 inch stroke) and front towers house a 10 ton hydraulic cylinder (10 inch stroke). CAUTION: 1. DO NOT use portable tower chain (3/8-12 with hook) on S21M front towers. The front towers require 1/2-12 tower chains with hooks. 2. The normal working range of 3/8 inch (10mm) tower chain is.4 to 2.4 tons (1.8 to 10.8 kn) on S21M pressure gauge with applied force to the chain of 7,400 lbs. (33kN). Proof test on this chain is 20,000 lbs (90kN). 3. DO NOT use pedestal as a step. 4. DO NOT allow S21M portable tower to come in contact with rear stiff leg assembly. 1. Slide pedestal to appropriate location on mainframe. NOTE: For best results, position pedestal so its housing is under or approximately under the pulling point on vehicle. If tower is positioned at side of mainframe, install pedestal locks to prevent pedestal movement. Use two locks if pedestal is positioned between rows of tie down holes and one lock if it is in line with a row of tie down holes. (See Figures 3 and 4.) A slight fore/aft adjustment of pedestal may be required so that locks fully engage tie down holes. (See Figure 3 inset.) If tower is positioned between the rear corners of the machine, DO NOT install pedestal locks. Pedestal need only be positioned far enough inward to allow tower pinning plate to align with tie down holes on rear crossmember. IMPORTANT: When winching vehicle on and off mainframe, DO NOT roll dead vehicle dollies over pedestal locks. 2. Attach tower to pedestal by inserting tower pivot pin (see Figure 5) into housing on underside of pedestal. Secure it with pin and clip. (See Figures 6 and 7). Pivot Pin Housing Figure 3 Figure 4 Figure 5 Figure 7 3. Align tower as per pull required and secure it to outer tie down hole on mainframe or to hole on rear crossmember. Use tower pin if pull can be made within 45 degree range shown in Figure 8. Use tie down bolt when pulling outside this range, or when pulling upward within 60 degree range shown in Figure 9. 45 Range Tower Pin Tower Base Pin Figure 6 Clip This pull requires tie down bolt. 60 Range Figure 8 Figure 9 2
Tower pin must project through tie down hole on mainframe (or rear crossmember) and fully engage hole on tower pinning plate. (See Figures 10 and 11.) If pull causes tower to lean, use shim(s) to fill gap between pinning plate and bottom surface of mainframe. (See Figure 12.) Tie down bolt must project through 3 1/2 x 4 inch tie down plate, tie down hole on mainframe (or rear crossmember) and hole on tower pinning plate. Use 3/4 inch nut and flat washer to secure tower to mainframe. (See Figure 13.) Tighten bolt to approximately 80 foot pounds of torque. Figure 14 Figure 10 Figure 11 Figure 12 5. Attach S21M s auxiliary hydraulic hoses to the portable tower s hydraulic connections. IMPORTANT: If hydraulic connections are not seated correctly, couplings may leak fluid or or may not allow fluid to pass through. Male and female connectors must be fully seated and then tightly threaded together. Secure black male and female couplers together and attach yellow male and female couplers together. (See Figure 15.) CAUTION: After connecting (or disconnecting) hydraulic hose, clean up any hydraulic fluid spillage. Portable Tower Auxiliary Hydraulic Hose 4. Remove loading ramp (see Figure 13 Figure 14) when moving auxiliary tower past end of treadway and when pull requires tower to be positioned where ramp is mounted. IMPORTANT: Reinstall ramp when tower is moved to another location. CAUTION: 1. Remove portable loading ramp only when it interferes with tower movement or tower pull at end of machine treadway. 2. Replace portable loading ramp as soon as tower is moved from end of treadway. Auxiliary Hose Valve (Black) Quick Couplers, Male (Yellow) Quick Couplers, Female Figure 15 3
6. Adjust tower collar and chain as per pull required. See Towers S21 EZ Liner Owners Manual. CAUTION: 1. DO NOT exceed 1.6 tons (7kN) hydraulic pressure when collar assembly is positioned 18 inches (457mm) or less from top of tower pipe. (See Figure 16.) 2. DO NOT use S21M portable towers to make pulls until vehicle is secured to mainframe with appropriate anchoring equipment. DO NOT use portable towers to anchor vehicle to mainframe. 18 (457mm) Figure 16 7. If making a pull at rear of machine install a movable crossmember and secure it to the machine using crossmember locks. Slide crossmember forward as far as locks will permit to prevent movement during the pull. (See Figure 17.) When using portable tower at rear of machine, follow bolting / pinning recommendations on Pages 2 and 3. NOTE: If it is difficult to pin or bolt tower through tie down holes in rear crossmember, adjust fore/aft position of crossmember to allow tower pin or tower bolt to drop into hole on tower pinning plate. If using a tie down bolt tighten to approximately 80 foot pounds of torque. ADJUSTMENTS Periodically check tower arm to mainframe gap. Position arm under mainframe at various locations along sides and at rear of machine. Measure gap between pinning plate and bottom of mainframe at each location. If narrowest gap exceeds 1/4 inch, add shim(s) (Part No. 532097) to each of the tower s rear caster assemblies until gap is 1/4 inch or less. To obtain shims, contact Chief Automotive Tehcnologies, Inc. 800-445-9262. To add shims: a. Lift tower s rear wheels off floor using tie down bolt installation procedure. (See Step 3 Page 2 and 3.) b. Remove caster assemblies, insert shim (see Figure 18) and reassemble. If pinning plate scrapes bottom of mainframe or crossmember, add washer to pivot pin assembly (see Figure 19 and its inset). Reassemble pivot pin assembly and reposition tower. If more clearance is needed, add a second washer. IMPORTANT: Check tower arm to mainframe gap whenever machine is moved. Figure 18 Figure 19 Crossmember Locks Figure 17 4
ACCESSORY APPLICATION A Chief down pull attachment (Part No. 772086) can be used on top of portable tower pedestal (see Figure 20) provided it is used as per instructions supplied with that accessory. Figure 20 CAUTION: DO NOT use down pull attachment on movable crossmembers. 5
