2.5 Personal Protective Equipment and Clothing
Always wear proper safety equipment as outlined below, not wearing such equipment CAN result in serious personal injury or possible death.
IMPORTANT CHECKS:
Anyone operating the leaf vacuum equipment MUST wear appropriate protective equipment and clothing to protect them from injury during operations.
PROTECTIVE EQUIPMENT:
1. Head Protection: Hard hats without under-chin strapping.
2. Eye Protection: Wraparound goggle type eye protection held in place
with an elastic band around the head or a hard hat mounted face shield,
which provides full protection of the face.
3. Eye protection must meet ANSI Z87.1 standards.
4. Hearing Protection: plug type or “muff type” ear protection should be
worn at all times while operating the unit.
5. Breathing Protection: Paper lter type dust masks should be worn to
protect from dirt and dust particles during the vacuuming process.
6. Reective Vests: Highly visible vests should be worn so motorists can
see see the operator in all weather and lighting conditions.
7. Work Gloves: Gloves should be worn to protect the hands and wrists
from debris.
8. Steel Toed Boots: should be worn to protect the feet.
Work clothes MUST be close tting, but not restrictive of movement, without any loose parts that could be entangled in any parts
of the leaf vacuum. This includes items such as jewelry, chains
and backpacks.

2.6 Work Site Preparation
Never place any part of the body under or behind guards or any
other visually obscured area.
Making sure the leaves are clear of possible dangerous material is
critical to safe vacuuming. Vacuuming up metal, glass, rocks or
other dangerous material CAN cause serious damage to the equipment or personal injury.
The following guidelines must be followed to insure safety.
1. An inspection of the leaves to be vacuumed must be done prior to the
vacuuming process. We realize that it is impossible to completely inspect
every inch of leaves being vacuumed, but it is imperative that all leaves be
inpsected for obvious dangerous material before vacuuming.
2. The operator should never be in the line of trafc, the operator should work
on the shoulder whenever possible.
3. The operators should place cones or other barriers to provide adequate
warnings to vehicles and pedestrians that vacuuming is in progress.
4. Strobe lights on the leaf vacuum and on the tow vehicle should be on at all
times for high visibility.
5. Conrm that all operators are wearing proper clothes and personal protec-
tive equipment.
6. Restrict all personnel, except the operator from the area near the leaf vacuum. DO NOT allow pedestrians, children or animals near the work area.
7. Make sure that the exhaust hose (if equipped) ts properly into the box
container so that all debris is blown into the box container.

3.1 Starting Engine
Always make sure the PTO is disengaged before
starting unit. (See gure 3b)
Thoroughly read and understand the safety and
pre-operating sections of this manual before staring the engine.
gure 3b
DO NOT start the engine in an enclosed building.
Proper ventilation is required before starting the
engine.
Review the Engine Operating Manual supplied with your
leaf vacuum for specic start-up, maintenance and operating instructions. It is especially important to review break-in
service procedures for brand new units.
Starting Procedure (refer to gures 3a and 3b):
1. Perform all the pre-starting, pre-operating checks outlined in the EOM and in this manual.
2. Make sure the PTO is disengaged as shown in gure
3b.
3. Turn the throttle control (g. 3a) counter-clockwise 2
revolutions.

3.1 Starting Engine, continued;
5. IMPORTANT: Do not operate the starter for more
than 30 seconds at a time. To do so may overheat the
starter. If the engine does not start the rst time, wait
at least 2 minutes before trying again. If the engine
fails to start after 4 attempts, see the trouble shooting
section of the EOM and this manual.
6. Turn the ignition switch all the way to the right, when the
engine starts release the ignition switch. It should spring
back to the rst position.
7. IMPORTANT: If the ignition switch is released before
the engine starts, wait until the starter and the engine
stop turning before trying again. This will prevent
possible damage to the starter and/or ywheel.
gure 3b
8. After the engine starts, continue to hold the Murphy Switch
in until the oil pressure gauge reads at least 15 psi. The
Murphy shut off switch will not allow the engine to operate below this level. If the gauge does not rise above 15
psi withing 5 seconds, stop the engine and determine the
cause. Normal operating oil pressure is 50 psi with oil at
normal operating temperature.
9. Check all gauges for normal engine opreration. If op-
eration is not normal, stop the engine and determine the
cause.
10. IMPORTANT: To assure proper lubrication, operate the
engine at or below 1200 rpm with no load for 1 -2 minutes. Extend this period 2 - 4 minutes when operating
at temperatures below freezing.
11. Watch the coolant temperature gauge. Do not place en-
gine under load until it is properly warmed up. The normal
engine coolant temperature range is 180 - 202 degrees F.

3.2 Engaging the PTO
Thoroughly read and understand the safety and
pre-operating sections of this manual before staring the engine.
PTO shown disengaged
Make sure the intake hose is properly attached
and make sure the front of the hose is clear of
any objects which could be inadvertently vacuumed during the PTO engagement process.
Review the Engine Operating Manual supplied with your leaf
vacuum for specic start-up, maintenance and operating instructions. It is especially important to review break-in service
procedures for brand new units.
gure 3d
safety assist cylinder
PTO shown fully engaged
Engaging the PTO (refer to gures 3b, 3c and 3d):
1. Perform all the pre-starting, pre-operating checks outlined in
the EOM and in this manual.
2. Start the engine as previously discussed in this manual and
in the EOM.
3. Once the engine has been allowed to thoroughly warm up
(engine temperature gauge should read at least 180 degrees) pull the throttle control until the engine reaches 1000
rpm.
4. Grasp the PTO handle (g. 3b) and slowly raise the handle.
NOTE: Some units have a PTO assist cylinder which engages the PTO at a specic speed in order to properly engage
the PTO. Because of this the PTO handle only needs to
be raised slightly, then the assist cylinder will take over and
engage the PTO automatically. (g. 3c)
