OPERATION (Pre-Ventilation Procedures)
Safe operation tips
(Ventilation Procedures)
BORING -Ventilation and breaching uses
"plunge cutting" which entails boring into a
structure. There is always a chance of
kickback even when the plunge cut is
expertly done. Keep the skid plate touching
the surface. Grasp both handles firmly and
bring the saw to full throttle. Using a steady
pressure, rock the tip of the saw into the
surface using the skid plate as a pivot point
between the system and the surface. Keeping
the weight of the system against the surface
with a firm grip will increase operator
comfort and control during this dangerous
operation.
CUTTING - After penetration, follow the
contour of the skid plate until the bar has
reached the approximate angle illustrated at
the right. Position the skid plate on the flat
surface, maintaining full throttle and steady
pressure while keeping the saw on the
surface. Pull the saw back, ripping through
the surface. Avoid cutting through joists and
rafters.
1. Follow all fire department procedures on safe
ventilation techniques and on avoidance of
cutting near gas and electric services.
2. Keep both hands on handles when engine is
running.
3. Always operate the saw at full throttle when
making a cut.
4. Always bury the tip of the cutting bar in the
cutting surface.
5. Make sure the skid plate is in contact with cutting
surface.
6. Avoid cutting above shoulder height and
overreaching.
