Mossberg International 81 Bolt Action - Manual (Page 4)

GENERAL INFORMATION AND MECHANICAL CHARACTERISTICS
The 817™ Bolt Action Rifle is designed to operate with .17 HMR cartridges only.
When the rifle leaves the factory, its metal parts are protected by a coat of very
adherent oil. This coating, especially inside of the barrel, must be removed before
using the rifle. The oil on the outside surfaces should also be removed when the
packing box has been opened because the oil is very sticky and it easily retains
dust and other solid impurities from the air.
OPERATING INSTRUCTIONS
Read and understand this entire manual and its safety warnings before firing
the rifle.
UNPACKING YOUR BOLT ACTION RIFLE
When shipped from the factory the bolt is removed from the action and packed
separately in the shipping carton. Before installing the bolt, visually and physically
inspect the inside of the barrel and receiver to ensure they are free of any excess oil,
grease or any obstructions. Obstructions of any kind can cause damage to the firearm
and may result in serious personal injury to the shooter and/or others nearby.
WARNING
Because this rifle can be used as a single shot, it will fire whether or not a
magazine is in the rifle if a cartridge is chambered.
RIFLE WILL FIRE WITH MAGAZINE OUT.
