SECTION 1: SAFETY For Your Own Safety, Read Instruction Manual Before Operating This Machine The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words intended to convey the level of importance of the safety messages. The progression of symbols is described below.

Log Splitter Body......................................... 1 B. Support Leg................................................. 1 C. Hardware Bag (Not Shown)......................... 1 — Carriage Bolts M8-1.25 x 10 .................. 5 — Hex Nuts M8-1.25...................................
Assembly The only assembly required is attaching the support leg to the splitter assembly. Components and Hardware Needed: Qty Carriage Bolts M8-1.25 x 10............................... 5 Hex Nut M8-1.25................................................. 5 To attach the support leg: 1. Carefully lay the splitter on its side, with the wiring box facing up. 2. Use the carriage bolts and nuts to secure the support leg to the splitter body as shown in Figure 5.
SECTION 4: OPERATIONS Operation Safety Damage to your eyes, lungs, and ears could result from using this machine without proper protective gear. Always wear safety glasses, a respirator, and hearing protection when operating this machine. Overview When you press the ON button, the electric motor pressurizes hydraulic fluid. When you push the control lever down, the pressurized fluid moves the pusher forward, pressing the log into the splitting wedge.
Basic Operations Locate the splitter as close as possible to the logs you will split. Refer to CIRCUIT REQUIREMENTS, on Page 8 for the maximum length of extension cords. Removing a Jammed Log To split a log: If a log does not split and becomes jammed on the splitting wedge, DO NOT try to clear it by hitting it from the side or kicking it; this can result in personal injury and damage the splitter. 1.
SECTION 5: MAINTENANCE Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury. Cleaning For optimum performance from your log splitter, clean it with a brush after every use and wipe it down occasionally with a rag. To prevent rusting, dry the log splitter thoroughly after every use. Checking/Adding Hydraulic Fluid The oil fill plug on the Model H8170/H8171 has a dipstick attached.
—If the oil level is at least halfway between the two grooves, no additional oil is needed –wipe the dipstick clean, return the plug, and tighten it. To change the hydraulic fluid: —If the oil level is close to the lower mark, add fluid through the oil plug hole until the level is at the top line, then tighten the fill plug. 2. 1.
Sharpening the Splitting Wedge Always wear protective, gloves when sharpening the splitting wedge. During the life of your log splitter, you will need to sharpen the splitting wedge perodically. When sharpening the wedge,m keep in mind that if you try and keep the wedge sharpened to a razor point (like an axe blade), you will greatly reduce the life of the wedge by always sharpening it.
