  • Chainsaw Safety
    QUICK CARDTM Chainsaw Safety Operating a chainsaw can be hazardous. Potential injuries can be minimized by using proper personal protective equipment and safe operating procedures. Before Starting a Chainsaw • Check controls, chain tension, and all bolts and handles to ensure that they are functioning properly and that they are adjusted according to the manufacturer’s instructions. • Make sure that the chain is always sharp and that the oil tank is full. • Start the saw on the ground or on another firm support. Drop starting is never allowed. • Start the saw at least 10 feet from the fueling area, with the chain’s brake engaged. Fueling a Chainsaw • Use approved containers for transporting fuel to the saw. • Dispense fuel at least 10 feet away from any sources of ignition when performing construction activities. No smoking during fueling. • Use a funnel or a flexible hose when pouring fuel into the saw. • Never attempt to fuel a running or HOT saw. Chainsaw Safety • Clear away dirt, debris, small tree limbs and rocks from the saw’s chain path. Look for nails, spikes or other metal in the tree before cutting. • Shut off the saw or engage its chain brake when carrying the saw on rough or uneven terrain. • Keep your hands on the saw’s handles, and maintain balance while operating the saw. • Proper personal protective equipment must be worn when operating the saw, which includes hand, foot, leg, eye, face, hearing and head protection. • Do not wear loose-fitting clothing. • Be careful that the trunk or tree limbs will not bind against the saw.

  • Harvesting Firewood from Your Woods
    Harvesting Firewood from Your Woods TOPICS: n Tree and Forest Biology (page 2) Basic concepts about how trees grow and the characteristics that make trees good or bad for firewood n Planning a Harvest (page 8) Which trees to cut for firewood and how to cut them safely n Processing Trees into Firewood ( p age 14) Techniques for splitting, drying and stacking wood Tree & Forest Biology Cutting trees for firewood requires careful management. The management decisions you make can either improve or harm the long-term health and productivity of your woodlands. Understanding how and where trees grow can aid your deci- sions about which trees to cut, and will lead to improvements in the overall health of your woodlands. Trees have several basic requirements for long-term survival: nutrients, space, water and sunlight. The competition for these resources will determine how well a tree grows and how long it will survive. Tree roots are responsible for the uptake of water and nutrients. The quality and quantity of these nutrients vary depending on the soil. Different trees are adapted to the dif- ferent soil types, from sand to clay. Clay and loam soils hold water and nutrients better than sandy soils. That means trees growing on sandy soils need to be able to grow in low nutrient and low moisture conditions. Each soil type can only support a limited number of trees, based on their size. Trees become stressed when there is too much competition for water and nutrients. To keep your forest healthy, some trees should be removed to make room for others to grow.

Price 75 cents Preface THOSE who want to be successful in any line of work or business must learn the tricks of the trade one way or another. For most occupations there is a wealth of published information that explains how the job can best be done without taking too many knocks in the hard school of experience. For logging, however, there has been no ade- quate source of information that could be understood and used by the man who actually does the work in the woods. This NORTHEASTERN LOGGERS' HANDBOOK brings to- gether what the young or inexperienced woodsman needs to know about the care and use of logging tools and about the best of the old and new devices and techniques for logging under the conditions existing in the northeastern part of the United States. Emphasis has been given to the matter of workers' safety because the accident rate in logging is much higher than it should be. Sections of the handbook have previously been circulated in a pre- liminary edition. Scores of suggestions have been made to the author by logging operators, equipment manufacturers, and professional forest- ers.
