sale were selected on the basis of their compatibility with the frame, fork and all other parts. Certain after-market products may or may not be compatible with your Razor Scream Machine. Consult your retailer or call Razor prior to modifying or replacing any component with a nonfactory specified product.
2. Proper fit and size adjustments 2. Fit. When properly adjusted, the rider should be able to pedal comfortably and steer with both feet remaining on the pedals at all times. If the rider has to stretch to reach the pedals or is too cramped, the seat should be adjusted fore or aft accordingly. WARNING: The age recommendation is only an estimate. If you are too small or too large to comfortably reach the pedals or handlebars, do not ride the Scream Machine.
WARNING: Cable operated brakes are very effective but must be adjusted and maintained on a regular basis. Check or have them checked and adjusted by a qualified mechanic. Worn brake parts, stretched or frayed inner wires or a kinked housing indicate brake service or parts replacement may be necessary for proper function. 4. Safety 4A. Helmets.
5. Safety check (before each ride) 5A. Loose parts. While straddling the Scream Machine, lift the front wheel off the ground two or three inches and let go so it can bounce on the ground. Does everything sound tight? There should not be any unusual rattles or sounds from loose parts or broken components. If you are not sure, ask an experienced mechanic to check. 5B. Cranks and pedals. Grasp the cranks and wobble them vigorously to check for play.
for assembly, it will assure the Scream Machine is properly put together and adjusted. ASSEMBLY NOTE: Refer to the list of tools required for assembly on page three of this manual. If you do not have the proper tools or understanding of the instructions in this manual, take your bike to a qualified mechanic for assembly, service or adjustments. 6A. Un-box. Remove contents from box. Remove the cardboard and/or plastic separators that protect the various component from damage during shipping.
Install both wheels on the Scream Machine by threading the axle bolts into the rear cross-beam of the Scream Machine frame. Using a 6mm Allen key, carefully tighten the axle while at the same time checking the wheel to see if it spins freely or if there is side-to-side play. If the wheel will not spin freely, loosen the axle about 1/4 to 1/2 turn and, using the supplied wrench, adjust the lock nut in or out until the wheel spins.
Figure 6. Both wheels installed. 6C. Install the fork. Insert the steering tube into the frame as shown in 7a and 7b. The steering bushings are preinstalled. Figure 7a. Figure 7b. Slide the handlebar and upper fork crown assembly into the fork legs as shown in figure 7c. Press both the spring buttons (arrows, 7d) and Figure 7c. Figure 7d.
continue to slide the handlebar assembly into the fork until the spring buttons engage the holes (A) as shown in figure 7e., and the steering tube extends through the upper fork crown (B). The fork stop must be positioned in the slot in the upper crown. The fit between the tubes is a close tolerance fit and may require a firm hand or taps with a rubber mallet to nudge the handlebar all the way into the fork. Figure 7e. Install the tensioning cap and adjusting screw as shown in figure 7f.
Figure 7g. Snug the adjusting screw. NOTE: The steering bushings are designed for long life and should require no maintenance. They do not require oil or any type of “wet” lubrication. If the steering becomes rough, disassemble, inspect and clean the bearing surfaces (soap and water is fine). Dry thoroughly and reassemble. Although the bushings and thrust washers are selflubricating, a light application of a dry-lube can be used to facilitate the anti-friction properties of the steering head bushings.
Figure 8c. 6E. Assemble the brake cable. The brake lever is preinstalled on the handlebars and the brake cable adjusting barrel may be either on the cable or threaded into the lever. Installing the cable requires placing the barrel (or ball) end of the cable wire into the socket on the lever and “threading” the wire through the slots in the adjusting barrel and jam nut as shown in the sequence 9a, 9b and 9c. Figure 9a. Figure 9b. Figure 9c.
Figure 10a. Figure 10b. WARNING: If you do not understand the procedure to connect the brake cable, we strongly recommend you seek the help of a qualified bicycle mechanic. If the brakes are not properly connected or adjusted the brakes may fail and you can be seriously injured.
Figure 11. If there is too much slack, the lever will go all the way to the handlebar without the brake being applied. If there is not enough slack, the brake will drag even when the lever is not pulled. Ideally, you want 2-3mm of play in the lever before the brake engages (as shown in figure 12). Figure 12. To adjust, loosen the lock ring and turn the barrel 1/4 to 1/2 turn to loose or tighten as required and squeeze the brakes to test. Continue to adjust until the proper cable slack is attained.
Figure 13. NOTE: The brake system requires a break-in period. You may have to repeat procedure 6F often during the first several hours of use. Repeat as necessary from thereafter to maintain proper brake function. The Scream Machine is supplied with a brake lever that adjusts to accommodate a variety of hand sizes. To adjust the brake lever so it is easier for shorter hands to operate the brake, turn the screw in the direction marked “B” in the photo below.
the responsibility of the user to periodically inspect the brake pads for excess wear and misalignment. If you do not understand how to adjust or realign the brake pads, we strongly recommend you seek the help of a qualified mechanic. If the brakes are not properly adjusted the brakes may fail and you can be seriously injured. 6H. Pedals, cranks and front wheel drive. The crankarms and pedals are supplied in the small parts box and must be installed.
