Operating Section
3.2 Engaging the PTO
Thoroughly read and understand the safety and
pre-operating sections of this manual before star-
ing the engine.
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 vacu-
umed during the PTO engagement process.
Review the Engine Operating Manual supplied with your leaf
vacuum for specific start-up, maintenance and operating in
-
structions. It is especially important to review break-in service
procedures for brand new units.
Engaging the PTO (refer to figures 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 de
-
grees) pull the throttle control until the engine reaches 1000
rpm.
4.
Grasp the PTO handle (fig. 3b) and slowly raise the handle.
NOTE:
Some units have a PTO assist cylinder which engag
-
es the PTO at a specific 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. (fig. 3c)
