The Sherman & Reilly BWT-1303 Tensioner uti-lizes precision machined urethane lined groovesfor ultimate control of conductors, both conven-tional and OPGW fiber optic. Each bullwheel iscontrolled by a fully adjustable, articulatedcaliper braking system with a ventilated bronzedisc. Options include manual retriever, hydraulicretriever, hydraulic spider rewind, spider levelwind, and hydraulic power pack to make it inde-pendent of any other power source. Conductorreels are easily changed by disengaging thebrake from the reel bar.
This manual is of no value if the operator doesnot read and understand the instructions andprecautions (before starting and trying to operatethe machine). The operator must be aware of themachine’s capacities and limitations. It is theoperator’s responsibility to watch for situationsand conditions which could affect the normalperformance of the machine and safety in thework area.
Publication of this manual and the safety pre-cautions in it does not in any way represent anall inclusive list. It is the operator’s responsibilityto make sure the machine is operated in accor-dance with all state and local safety require-ments and codes, including all applicable OSHA(Occupational Safety and Health Act) and ANSI(American National Standards Institute) regulations.
Should a problem or unsafe condition arise,shut the machine down using the normal shut-down procedure. In the event of an emergency,use the emergency stop procedure.

REEVING
The tensioner is designed for the conductor tofeed off the bottom of the reel and toward thefront of the machine.
When reeving the bullwheels, it is recommend-ed that:
1. All three disc brakes be disengaged, so thebullwheels and conductor reel can beturned by hand.
2. A synthetic rope may be reeved in the bull-wheels and used to pull the conductorthrough the bullwheels.
3. Standing at the front of the machine, facingtoward the rear of the machine, the con-ductor should lead through the fairlead intothe bottom of the left hand groove of thelower bullwheel. The conductor should bereeved in each bullwheel groove and leavethe top right hand groove of the upper bull-wheel going to the pole over the rear of themachine.
Following this procedure will lessen thetendency to loosen the strands of right handlay conductor (standard for aluminum con-ductor) as the conductor passes through thebullwheel.

Section 3 • OPERATION
TENSIONING
If the situation permits, it is better to set thebrakes moderately and adjust upward to thedesired stringing tension. For smoother opera-tion, it is recommended that the over-spin brakeon the conductor reel be set as lightly as the jobwill permit. The tensioning force should be gen-erated and regulated by the bullwheel brakes.The bullwheel brakes should be adjusted evenly.If one brake appears to be heating more than theother, then the braking force on it should bedecreased and the braking force on the othershould be increased.
Keep hands, arms, and other parts of the bodyand all clothing away from all moving parts orsevere injury is possible.
On all brakes, rotate the handle clockwise toincrease tension and counter-clockwise todecrease tension.
The machine is equipped with reel locking pins.They should be engaged when transporting thereel or when leaving the conductor under ten-sion for long periods of time.

INSTALLING PULLING GRIP
1. Select the correct size grip. (Refer to manu-facturer’s chart or specifications.)
2. Use a feed tube or contain the end of therope or conductor. Slide the grip into place.
The conductor or rope should be installedup to the elbows of the aluminum shouldersto assure full and complete gripping action.
3. Lock the mesh on the tail end of the grip tothe rope or conductor, using two punch-lokbands, positioned 1" to 2" from tail of grip.
4. It is a good practice to apply tape over thebanded grip tail only, to assure smoothpassage through the sheaves. Do not tapethe entire grip.
NOTE
The spider rewind system is used to wind up spi-der line or pilot rope when pulling the bull linethrough the stringing blocks. The rewind systemutilizes a levelwind to ensure smooth even dis-tribution of the pilot line onto the spider reel.
1. Move the spider rewind control to pull theline over the top of the drum. The levermust be held to operate the unit.
2. As the spider line/pilot line goes on the reel,move the levelwind control back and forthgradually to wind the cable on the reelevenly.

SERVICE REQUIREMENTS
CALIPER DISC BRAKES ONREEL CARRIER/BULLWHEELThe brake linings should be inspected weeklyand replaced before the rivet heads damage thebrake disc.
AXLEThe wheel bearing reservoirs should be visuallyinspected before towing the machine and main-tained at the level line with SAE-90, SAE 80W-90, SAE 80W-85W-90, or SAE 75W-90 Hypoidgear oil. The wheel bearings should be replacedas necessary.
WHEEL MOUNTINGIt is important to maintain proper torque specifi-cations to ensure safe and secure attachment ofthe wheel to the hub.
Star lug nuts by hand to prevent cross threading.
Tighten lug nuts in three stages using a cross starpattern. When using clamp ring and 90° conenuts, tighten the wheel nuts to a final torque of200 ft. lbs.
The proper torque must be maintained by check-ing every 50 miles for the first 200 miles, thenper periodic maintenance and after every chargein wheel mounting.
TRAILER BRAKESThe brakes are self-adjusting. When the leadingshoe leaves the anchor pin during a reversebrake application, the adjuster cable pulls theadjuster pawl upward to engage the next tooth ofthe adjuster star wheel if adjustment is necessarydue to normal wear. To release the shoes, theadjuster pawl must be pulled away before thestar wheel can be turned backward to decreasebrake adjustment. To obtain access to theadjuster, remove the bottom half of the dustcover. When reinstalling the dust cover, tightento five ft. lbs.
Over torquing may damage the cover.
Upon reinstallation, the shoes should be adjust-ed to the point of lightly dragging the drum andwith approximately .010" of clearance on theshoe with the most shoe to drum clearance mea-sured at the 3 or 9 o’clock position.
The brakes should be checked for adjustmentevery 3000 miles or six months and the liningsinspected for wear and contamination every5000 miles and replaced as necessary. Actualservice may indicate more frequent adjustments.
