WARNING

DANGER

1.4.1 Use EXTREME caution when mowing and/or turning on slopes as loss of traction and/or tip-over could occur. The operator is r esponsible for safe operation on slopes.

DANGER

POTENTIAL HAZARD ♦ Mowing on wet grass or steep slopes can cause

sliding and loss of control. WHAT CAN HAPPEN ♦ Wheels dropping over edges, ditches, steep banks,

or water can cause rollovers, which may result in

serious injury, death or drowning. HOW TO AVOID THE HAZARD

♦ Do not mow slopes when grass is wet. ♦ Do not mow near drop-offs or near water. ♦ Do not mow slopes greater than 15 degrees. ♦ Reduce speed and use extreme caution on slopes. ♦ Avoid sudden turns or rapid speed changes.

• Use a walk behind mower and/or a hand trimmer near drop-offs, ditches, steep banks or water. This area can be dangerous, see Figure 1.

FIGURE 1

SAFE ZONE FOR MOWING

• Progressively greater care is needed as the slope increases.

• Always avoid sudden starting or stopping on a slope. If tires lose traction,

disengage the blades and proceed slowly off the slope.

• Avoid sudden starts when mowing uphill. Mower may tip backwards.

• Be aware that loss of traction may occur going downhill. Weight transfer to

the front wheels may cause drive wheels to slip and cause loss of braking and steering.

• Watch for ditches, holes, rocks, dips, and r ises t hat change the operating angle, as rough terrain could overtur n the machine.

• Remove or mark obstacles such as rocks, t r ee lim bs, et c. from the mowing area. Tall grass can hide obstacles.

• The operating characteristics of the machine will change with the Ultra Vac QDS installed. The stability and traction of the machine will change as the Ultra Vac QDS hopper fills with grass clipping s. Use pr ogressively greater care on slopes as the hopper fills.

• Always install and remove the Ultra Vac QDS, including counterweights, as instructed. Failure to do so will cause a reduction in stability or tr act ion. Do not operate the mower with only a portion of the Ultra Vac Q DS inst alled.

1.5 SAFETY SIGNS

1.5.1 Keep all safety signs legible. Remove all gr ease, dir t and debris from safet y signs and instructional labels.

1.5.2 Safety signs must be replaced if they are missing or illegible.

1.5.3 When new components are installed, be sure that current safety signs are affixed to the replaced components.

1.5.4 New safety signs may be obtained from your authorized Exmark equipment dealer or distributor or fr om Exmar k Mfg. Co. Inc.

1.5.5 Safety signs may be affixed by peeling off the backing to expose the adhesive surface. Apply only to a clean, dry surface. Smooth to remove any air bubbles.

1.5.6 Familiarize yourself with the following safety signs and instruction labels. They are critical to the safe operation of your Exmark Ultra Vac QDS.

3.7 ADJUSTMENTS:

Your Ultra Vac QDS was adjusted at the factory to operate properly. However, there are

two basic adjustments that can be made, should your unit require them:

3.7.1 Door closi ng: The closing of the door is controlled by the two hinge links (Figure 9 – A). The length of the hinge links can be changed to provide complete closing of the door and reasonable forc e on t he handle t o lat ch or unlatch the door. Lengthen the links to reduce the force. Shorten the links to increase the force. The left and right sides m ust be appr oximat ely eq ual. With the door closed, bot h links should be slightly tight t o minimize rattling.

3.7.2 Door openi ng: After adjusting the hing e links for door closing, t he hinge stops (Figure 9 – B) can be adjusted to obtain m aximum door opening. The stop plates should be adjusted so that the door link contact s t hem when the upper t ube of the door frame is within .25” (6.4 mm) ± .125” (3.2 mm) from the lower lip of the molded hood. Both left and right st ops m ust make contact when the door link arm is at this position.

4. OPERATION

4.1 PRE-START

4.1.1 Read the operator’s manual for your mower and fam iliar ize yourself with all controls before operating t he machine. Make sure that you understand the controls, their locations, their functions, and their safety requirements.

4.1.2 Ensure the blower, belt cover, door m esh, tube and hopper are in good condition, properly attached, and latched.

NOTE: When mowing in areas with sandy soil, use low lift blades on the cutting deck and higher cutting heights to minimize wear on the blower component s.

4.2 MOWING

4.2.1 The Ult r a Vac QDS blower operates when deck drive is engaged. Be sure that all persons are clear of the m ower deck bef ore engaging the cutting blades. Set the throttle to “m idway” position. Pull out ward on t he PTO switch to the “ROTATE” position. Accelerate to full throttle to begin mowing.

4.2.2 To disengage the PTO and blower, set the throttle to “midway” position. Push in on the PTO switch to the “STOP” position to stop the cutting blades and blower. The cutting blades will require a slightly longer amount of time t o com e to a complete stop when the blower is installed on the deck. Verify that all rotation indicators have stopped before clearing blower assembly or mower deck.

4.2.3 To em pt y the hopper , first shut off deck drive, Lift up on the handle to open the door and empty the hopper. If the unit i s t o be dri ven onto a truck or t r ai ler

with the hopper full, always back the unit up the ramp. This will reduce the chance of rearward tip up. See secti on 4. 4 Transporti ng f or addi t ional information regarding loading a unit on a truck or t r ai l er.

are designed to be installed or removed in their entirety. Do not operate the mower wi t h only a portion of the Ultra Vac QDS installed.

4.3.11. The machine can now be used for side discharge mowing.

4.4 TRANSPORTING

4.4.1 Transporting a Unit: Use a heavy-duty trailer or truck t o transport the machine. Lock brake and block wheels. Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes. Be sure t hat t he trailer or truck has all necessary lighting and marking as required by law. Secure a trailer with a safety chain.

POTENTIAL HAZARD ♦ This unit does not have proper turn signals, lights, reflective

markings, or a slow moving vehicle emblem. These items

are required to drive on a public street or roadway. WHAT CAN HAPPEN ♦ Driving on a street or roadway without such equipment is

dangerous and can lead to accidents causing personal injury. ♦ Driving on a street or roadway without such equipment may

also be a violation of State laws and the operator may be

subject to traff ic tickets and/or fines. HOW TO AVOID THE HAZARD ♦ Do not drive a unit on a public street or roadway.

CAUTION

POTENTIAL HAZARD ♦ Loading a unit on a trailer or truck increases the possibility of

backward tip-over. WHAT CAN HAPPEN ♦ Backward tip-over of the unit could cause serious injury or

death. HOW TO AVOID THE HAZARD

♦ Use extreme caution when operating a unit on a ramp. ♦ Use only a single, full width ramp; DO NOT use individual ramps

for each side of the unit. ♦ If individual ramps must be used, use enough ramps to create

an unbroken ramp surface wider than the unit. ♦ DO NOT exceed a 15° angle between ramp and ground or

between ramp and trailer or truck. ♦ Avoid sudden acceleration while driving unit up a ramp to avoid

tipping backward. ♦ Avoid sudden deceleration while backing unit down a ramp to

avoid tipping backward.

Ramp should be long enough so that the angles between the ramp and t he ground

Loading a Unit: If the unit is to be dri ven onto a truck or t r ai ler with the hopper

full, always back the unit up the ramp. This will reduce the chance of rearward tip up. Use extreme caution when loading units on trailer s or trucks. One f ull width

ramp that is wide enough to extend beyond the rear tires is requir ed instead of individual ramps for each side of the unit. The lower rear section of the tractor frame extends back between the rear wheels and serves as a stop for tipping backward. Having a full width ramp provides a surface for the frame members to contact if the unit starts to tip backward. If it is not possible to use one full width ramp, use enough individual ramps to simulate a full width continuous ramp.

and the ramp and the trailer or tr uck do not exceed 15°. A steeper angle may cause mower deck components to get caught as t he unit moves from ramp to trailer or truck. Steeper angles m ay also cause the unit t o t ip backward. If loading on or near a slope, position the trailer or truck so it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle. The trailer or truck should be as level as possible.

WARNING

DO NOT attempt to turn the unit while on the ramp, you may lose control and drive

off the side.

Avoid sudden acceleration when driving up a ramp and sudden deceleration when

backing down a ramp. Both maneuvers can cause the unit to tip backward. Dump contents of hopper before t r anspor t. Do not transport the unit with the hopper full.

Your Ultra Vac QDS was adjusted at the fact or y to oper at e pr operly. However, there are two basic adjustments that can be made, should your unit require them:

9 – A). The length of the hinge links can be changed to provide complete closing of the door and reasonable forc e on t he handle t o lat ch or unlatch the door. Lengthen the links to reduce the force. Shorten the links to increase the force. The left and right sides m ust be appr oximat ely eq ual. With the door closed, bot h links should be slightly tight t o minimize rattling.

(Figure 9 – B) can be adjusted to obtain m aximum door opening. The stop plates should be adjusted so that the door link contact s t hem when the upper t ube of the door frame is within .25” (6.4 mm) ± .125” (3.2 mm) from the lower lip of the molded hood. Both left and right st ops m ust make contact when the door link arm is at this position.

6. Tips and Troubleshooting

Your Exmark Ultra Vac QDS has been designed to be t he m ost productive bagging system on the market. The following tips have been collected to help you get the most out of your Ult r a Vac QDS right from the st ar t.

6.1 When mowing in areas with sandy soil, use low lift blades on the cutting deck and higher cutting heights t o minimize wear on the blower components.

6.2 When mowing in wet conditions, such as just af ter a rain or in heavy dew, use low lift blades on the cutting deck to minimize plugging of t he blower.

6.3 When the bags g et full, the sound of the blower will change and there will be slight blowout from the front right corner of the deck . Emptying the bags at this point will minimize the potential for the tube to plug.

6.4 If there is excessive blowout from the deck, check t o make sure that the rear screen in the hood is clear of grass build up. I t is recommended that the screen and mesh portions of the bags be cleaned regularly to maintain proper air flow. This is especially important in wet conditions.

6.5 During dry conditions check engine air cleaners and clean cooling f ins mor e frequently. The Ultr a Vac QDS has been designed to minimize the impact of dust and debris on the mower, but bagging can be a dir t y environment.

6.6 During dry conditions, switching to a lower lift blade may reduce blowout without hurting quality of cut.

6.7 Maintaining a ground speed that does not pull down the engine RPM will allow for the highest productivity and best quality of cut . Bogging the engine RPM down by going too fast will cause plugg ing and quality of cut issues.

6.8 When storing t he Ult ra Vac QDS, it is recommended that any build up in the blower be cleaned out. Dry grass build up may cause problems with the impeller when the unit is put back into operation.

6.9 If the blower drive belt snaps or breaks frequently, check the alignment of the idler arm per section 5. An arm that is bent out of position can cause the belt to jump off of the idler and be cut by the sheaves.

6.10 If the idler pulley contacts the deck sheave, check the alignment of the idler arm per section 5. Also check the mounting t ube on t he deck and the mounting pin on the blower for bending or excessive wear. This condition is more lik ely to occur with smaller deck sizes.

6.11 T he condit ion of the belt drive is critical to proper operat ion. A sticking idler arm or worn belt may cause plugging or blowout. Replace the belt when the idler arm is riding on or near the stop.

6.12 Anti- blowout k it s are available for leaf collection. They help to pr event “ chasing” the leaves. To reduce “plowing” leaves, raise the deck slightly.
