Following "Bel t Di ag ra m" i ns er t #6 and #7 Glute n Ass embl ie s into Body cavi ty and se cu re with #10 Pi vot Rod. (Note: Use 5/8 WI Was he rs to shi m #6 and #7 Assemblies left or right so that their respective #6A Arms are centered between th ei r res pe ct i ve #18 Pul le ys) Now you must pr op er ly adjus t #14 Idl er Wheel units you as se mbl ed abo ve. Slide this Wheel unit re ar wa rd (or forwar d as the ca se may be) so that the Clutc h con tr ol hand le s can move for ward and backwa rd a to ta l di s tan ce of ap pr oxi mat el y 3" as mea su re d on the ends of Hand les . Make tlis t ra ve l equal in both co nt ro l handles and the n tig hten each 3/8 Cap Scr ew. (Check for pro per 90° angle as explained in Step #10). NOTE: Check to make su r e tha t al l four #9 Guide s ri de with the "hooked end" to the outsi ds of each #20 Bel t.
In proper operation as the #14. Idler moves away fromtightening a #20 Belt, simultaneously the "hooked end" of the #9 Guide should start to hit the backside of the #20 Belt and start to pull it in to eliminate any excessive slack. 12. From inside slide a 3/8-16 x 1-1/2 Carriage Bolt into slot of #1K Bracket. Slide on one 1/2" WI Washer followed by three 3/8 WI Washers and #13 Idler Wheel. Secure with 3/8-16 Stollach Nut. 13. Insert 3/16 sq x 7/8 Key into hub of #17 Pulley and slide onto PTO of Engine hub to outside. Slip 5/16-24 x 1 Cap Screw into 5/16 WI Washer, then into "tight" loop end of #8 Engine Belt Guide followed by 5/16 Washer. M ake two Guide Assemblies like above and screw them into the two rear threaded holes in Engine case. Note that 90° Bend end is pointing away from Engine. 14. Lower Engine into Body cavity (PTO to the left) and fasten front and rear of Engine to #1J Mount using four 5/16-18 x 3/4 Cap Screws and Lock Washers. (Nuts are already welded into the Mount) 15. Insert 3/8-16 x 1-1/2 Cap Screw into #13 Idler Wheel, then into three 3/8 W I. Washers and finally into inside hole of #1L Arm; secure on other side with 3/8-16 Stollach Nut. (Note on Drawing that #13 Wheel is next to inside face of #1L Arm) 16. Using the #1J M ount as a "straight-edge" guide, align the #17 Engine Pulley and #16 Pulleys with the two fixed #13 Idler Wheels. W hen aligned, lock all set screws noting that Keys are centered in hub of their respective Pulleys. Slip the #19 Belt over the #17, 16 and 13 Pulleys following the "Belt Diagram". 17. Slip 1/4-20 x 3/4 Cap Screws into each end of #22 Spring. Slide one end of Screw into the inside 1/4" hole in #1MHandle and the other end into the outside 1/4" hole in rear of.#lEL Plate. Secure both Screws with 1/4-20 Stollach Nuts. (Note how lowering #1MHandle - under spring tension - causes #13 Pulley on #1L Arm to engage and tighten #19 Belt) At this point (Belt under tension) rotate the top and bottom#8 Engine Belt Guides so they are approx. 1/8" away from the #19 Belt. Tighten both 5/16-24 x 1 Cap Screws. (Check Drawing for correct placement of #8 Guides) 18. Now raise #1MHandle and engage it behind #1O Clip to hold it. Loosen the 3/8-16 x 1-1/2 Carriage Bolt holding #13 Idler on #1K Bracket. Locate the #13 Idler so that when the above #1M Handle is in the raised position, the #19 Belt is slackened sufficiently to allow the #17 Engine Pulley to slip. Tighten the Carriage Bolt after you have made this adjustment. 19. (Note: You will have to readjust the above after the first hour of operation due to the natural "break-in" action of the Belt).
20. Mount #1P Brace over rear of #1ER and 1EL Plates by engaging the two 5/16 W eld Screws into the two forward holes of #1P Brace. Align two rear 3/8 holes in #1P Brace with holes rear of #1ER and 1EL and secure with 5/16-18 x 3/4 Cap Screw, Lock Washer and Nut.
21. M ount #24 Throttle Wira.through 9/16 dia. Hole in #1P Brace and secure below with nut provided. Loop end of Wire down around bottom of Carburetor and enter the end into the clip provided on left side of carburetor. (See Sketch "A" for proper installation of remaining Wire end) NOTE: Position Wire so that pulling up on the Throttle will choke the Engine and pushing the Throttle all the way down will close the small switch which,shuts off the Engine. -r22.Pull up on Engine starter rope and tie a "loop knot" to keep it fromretracting. Remove handle from rope and insert rope through bottom of remaining hole with grommet in#lP Brace. Above, reassemble handle.on rope end and remove knot to allow rope to recoil. . ; 23. At this point check Engine manual and fill crankcase and gas tank as per instructions. ' Take can of oil and generously lubricate oilers in the #3 Drive Wheel Assemblies. Repeat this oiling periodically to renew the "Oilite" bearings' oil supply. The #13 and #14 Idler Wheels and #12 Bearings all have sealed ball bearings and are lubricated for life. 24. M ount the #27 Seat to the #2 Cover using four 1/2-13 x 1 Cap Screws, Lock Washers and Nuts. Slip vinyl cover and cushion over seat and tie draw-string. Set #2 Cover over the four protruding 5/16-18 W eld Screws and secure with four 5/16-18 W ing Nuts. Slip #25 Handgrips on ends of #6B and 7B Handles. OPERATION: Before starting Engine check to see that the #1MHandle is raised and engaged behind the #1O Clip welded to #1EL Plate. Next pull up and set Throttle so that Engine has sufficient gas to start - pull all the way up to choke in cold weather. Start Engine and lock Throttle setting by twisting handle 1/4 turn clockwise to hold position. Climb on the Skat and with your right hand keeping the Control Handles in the center or neutral position, release the Safety Clutch Handle with your left hand to set transmission in motion. Now firmly holding a Control Handle in each hand you can move forward by pushing forward on both Handles; rearward by pulling back on the handles. M ake your turns by simultaneously pushing one Control Handle forward and pulling the other rearward. NOTE: All these actions should be done slowly and carefully for maximum safety and elimination of jerky motions.
NOTE:
For maximum safety both Control Handles must be held by the operator either by a single hand or with both hands while the transmission system is in motion. Therefore, with the transmission in motion the Control Handles should never be left unattended or the natural action of the transmission will cause them to occasionally bounce back and forth. If this condition takes place it can be quickly stopped by disengaging the transmission system with the Safety Clutch Handle and then re-starting.
SAFETY: LAND - As the Mini-Skat is a completely different type of vehicle to operate, it is advisable that in the beginning you take the utmost of caution. Practice handling it on an open, level piece of ground until you get the "feel" of it. W hen climbing up hills or going through unfamiliar areas always take it slowly. Even though the S k a t is extrem ely stab le, it can still b e tip p ed or d am a ge db y irrespo nsible opera-
W ATER - From the outset, it must be understood that the Mini-Skat's amphibious use must be limited exclusively to crossing calm water. The Skat is purposely designed "front heavy" to give it the greatest stability climbing hills. Hence for water travel it is advisable to place whatever cargo you wish to carry (tent, sleeping bag, etc.) to the rear to give you a level ride in water. Always enter the water as level with the water as possible - that is never enter the water while coming off a steep bank as you may "swamp" the Skat due to the severe angle of entering. The same is true on leaving the water - don't try to climb a steep bank to get out as the "tail" of the Skat may swamp. The Skat's operation in water is quite similar to that of a "Jon Boat". Hence the same loading and safety precautions apply. Most States require the Skat to be registered as a boat if you plan on taking it on inland waterways. Also the standard Coast Guard life preserver and fire extinguisher rules apply to the Skat. NOTE: Tire Chains are an option well worth the expense as they give you a steel biting grip on slippery surfaces and also provide additional propulsion in water.
